Should I solve leetcode using bash scripting? Or are there real world problems to solve using bash?
Yeah my job doesn't have anything to script/automate using bash, yeah it doesn't truly. I can't see how bash can be useful. Like it could be use for data science, analysis, visualization etc, however, it breaks my heart because I see no body teaching it. I get a book called data science at the command line but it's too complicated to follow. I stopped at docker image in 2nd chapter. I could not fathom what was going on...
Please help me. Should I just start solving leetcode?
There is another book called cyberops with bash. However, I am not dive deep into cybersecurity at this moment. I want something similar to this stuffs.

Watch out for Implicit Subshells
Bash subshells can be tricky if you're not expecting them. A quirk of behavior in bash pipes that tends to go unremarked is that pipelined commands run through a subshell, which can trip up shell and scripting newbies.

help's Command List is Truncated, Any way to Show it Correctly?
Hi all
If you run help,
you get the list of Bash internal commands.
It shows it in 2 columns, which makes some of the longer titles be truncated, with a ">" at the end.
See here:

Weird issue with sed hating on equals signs, I think?
Hey all, I been working to automate username and password updates for a kickstart file, but sed isn't playing nicely with me. The relevant code looks something like this:$username=hello$password=yeetsed -i "s/name=(*.) --password=(*.) --/name=$username --password=$password --/" ./packer/ks.cfg
Where the relevant text should go from one of these to the other:user --groups=wheel --name=user --password=kdljdfd --iscrypted --gecos="Rocky User"user --groups=wheel --name=hello --password=yeet --iscrypted --gecos="Rocky User"
After much tinkering, the only thing that seems to be setting this off is the = sign in the code, but then I can't seem to find a way to escape the = sign in my code! Pls help!!!

Sending mail through bash, is mailx still the right option?
I'm writing a script that will be run via cronjob late at night, and I'd like for it to email the results to me.
When I use man mail, the result is mailx. I can't find anyone talking about mailx in the last decade, though! Is this still the best way to send mail through bash, or has it been replaced with someone else?
If mailx is still right, does the [-r from_address] need to be a valid account on the server? I don't see anything about it being validated, so it seems like it could be anything :-O Ideally I would use root@myserver.com, which is the address when I get other server-related emails, but I'm not sure that I have a username/password for it.
This is the man for mailx:

Understanding bash pipes to chain commands
I'm using this to get the most recently updated file in a MySQL directory:
ls -ltr /var/lib/mysql/$DB/* | tail -1
The result looks like this:
-rw-rw---- 1 mysql mysql 2209 Dec 7 2020 /var/lib/mysql/foo/bar.MYI
The goal is to only back up the database if something has changed more recently than the last backup.
Next I'm trying to extract that date as an ENOCH timestamp, so I used this (using -tr to just get the filename):
ls -tr /var/lib/mysql/$DB/* | tail -1 | stat -c "%Y %n"
This throws an error, though:
stat: missing operand
Using -ltr threw the same error.
I'm only guessing that stat's not correctly getting the output of tail -1 as its input?
I can do it in 2 lines with no problem (typed but not tested):
most_recent=$(ls -ltr /var/lib/mysql/$DB/* | tail -1)
last_modified=$(stat -c "%Y %n" "/var/lib/mysql/DB/$most_recent" | awk '{print $1}')
But for the sake of education, why doesn't it work when I chain them together? Is there a built-in variable to specify "this is the output from the previous command"?

Is it better to loop over a command, or create a separate array that's equal to the results of that command?
This is how I do a daily backup of MySQL:
for DB in $(mysql -e 'show databases' -s --skip-column-names)
do
mysqldump --single-transaction --quick $DB | gzip > "/backup/$DB.sql.gz";
done
I have 122 databases on the server. So does this run a MySQL query 122 times to get the results of "show databases" each time?
If so, is it better / faster to process to do something like this (just typed for this post, not tested)?
databases=$(mysql -e 'show databases' -s --skip-column-names)
for DB in ${databases@}
do
mysqldump --single-transaction --quick $DB | gzip > "/backup/$DB.sql.gz";

Sed | replacing variable with new value, along with escaping
I'll put the basics of the script down:
VERSION=$(git show -s --date='format:%Y.%m.%d' --format='%cd+%h' | sed "s/^0*//g; s/\.0*/./g" | sed 's/[][ \~`!@#$%^&*()={}|;:'"'"'",<>/?]/\\&/g')
sed -i "s/VERSION_STRING = .*/VERSION_STRING = \x22${VERSION}\x22/" ./app/version.py
VERSION, and then transfer that new value using sed and replace the current value in the file.sed: -e expression #1, char 37: unknown option to `s'
VERSION = "1.0.0"
ANOTHER = "My string with @ # $ special %^& chars"
ANOTHER which will contain special characters. And unless I escape them using the sed rule at the top which is being used on VERSION, it'll just error out.
[UPDATE] forkrun v1.4 released!
I've just released an update (v1.4) for my [forkrun](https://github.com/jkool702/forkrun) tool.
For those not familiar with it, `forkrun` is a ridiculously fast\*\* pure-bash tool for running arbitrary code in parallel. `forkrun`'s syntax is similar to `parallel` and `xargs`, but it's faster than `parallel`, and it is comparable in speed (perhaps slightly faster) than `xargs -p` while having considerably more available options. And, being written in bash, `forkrun` natively supports bash functions, making it trivially easy to parallelize complicated multi-step tasks by wrapping them in a bash function.
forkrun's v1.4 release adds several new optimizations and a few new features, including:
1. a new flag (`-u`) that allows reading input data from an arbitrary file descriptor instead of stdin
2. the ability to dynamically and automatically figure out how many processor threads (well, how many worker coprocs) to use based on runtime conditions (system cpu usage and coproc read queue length)
3. on x86_64 systems, a custom loadable builtin that calls `lseek` is used, significantly reducing the time it takes forkrun to read data passed on stdin. This brings `forkrun`'s "no load" speed (running a bunch of newlines through `:`) to around 4 million lines per second on my hardware.
Questions? comments? suggestions? let me know!
***
\*\* How fast, you ask?
The other day I ran a simple speedtest for computing the `sha512sum` of around 596,000 small files with a combined size of around 15 gb. a simple loop through all the files that computed the sha512sum of each sequentially one at a time took 182 minutes (just over 3 hours).
`forkrun` computed all 596k checksum in 2.61 seconds. Which is about 4300x faster.
Soooo.....pretty damn fast :)

How to Replace a Line with Another Line, Programmatically?
Hi all
I would like to write a bash script, that takes the file /etc/ssh/sshd_config,
and replaces the line #Port 22
with the line Port 5000.
I would like the match to look for a full line match (e.g. #Port 22),
and not a partial string in a line
(so for example, this line ##Port 2244 will not be matched and then replaced,
even tho there's a partial string in it that matches)
If there are several ways/programs to do it, please write,
it's nice to learn various ways.

Final script to clean /tmp, improvements welcome!
I wanted to get a little more practice in with bash, so (mainly for fun) I sorta reinvented the wheel a little.
*Quick backstory:*
My VPS uses WHM/cPanel, and I don't know if this is a problem strictly with them or if it's universal. But back in the good ol' days, I just had session files in the /tmp/ directory and I could run tmpwatch via cron to clear it out. But awhile back, the session files started going to:
# 56 is for PHP 5.6, which I still have for a few legacy hosting clients
/tmp/systemd-private-[foo]-ea-php56-php-fpm.service-[bar]/tmp
# 74 is for PHP 7.4, the version used for the majority of the accounts
/tmp/systemd-private-[foo]-ea-php74-php-fpm.service-[bar]/tmp
And since \[foo\] and \[bar\] were somewhat random and changed regularly, there was no good way to set up a cron to clean them.
cPanel recommended this one-liner:
find /tmp/systemd-private*php-fpm.service* -name sess_* ! -mtime -1 -exec rm -f '{}' \;
but I don't like the idea of running `rm` via cron, so I built this script as my own alternative.
*So this is what I built:*
My script loops through /tmp and the subdirectories in /tmp, and runs tmpwatch on each of them if necessary.
I've set it to run via crontab at 1am, and if the server load is greater than 3 then it tries again at 2am. If the load is still high, it tries again at 3am, and then after that it gives up. This alone is a pretty big improvement over the cPanel one-liner, because sometimes I would have a high load when it started and then the load would skyrocket!
In theory, crontab should email the printf text to the root email address. Or if you run it via command line, it'll print those results to the terminal.
I'm open to any suggestions on making it faster or better! Otherwise, maybe it'll help someone else that found themselves in the same position :-)

lolcat reconfiguration help needed please
Was hoping you could help out a total noob. You may have seen this script - lolcat piped out for all commands. Its fun, it's nice, but it creates some unwanted behavior at times. Its also not my script (im a noob). However, i thought, at least for my purposes, it would be a better script if exclusion commands could be added to the script, for example this script 'lolcats' all commands, including things like 'exit' and prevents them executing. So i'd like to be able to add a list of commands in the *.bashrc script that excludes lolcat from executing, such as 'exit'. Any help is appreciated. Thanks.
lol()
{
if -t 1 ; then
"$@" | lolcat
else
"$@"
fi
}
bind 'RETURN: "\e1~lol \e[4~\n"'
or this one has aliases created, but i'd like to do the opposite, instead of adding every command to be lolcat, create an exclusion list of commands not to be lolcat.
lol()
{
if [ -t 1 ; then
"$@" | lolcat
else
"$@"
fi
}
COMMANDS=(
ls
cat
)
for COMMAND in "${COMMANDS@}"; do
alias "${COMMAND}=lol ${COMMAND}"

Any way to tell if script is ran via command line versus cron?
Inside of a bash script, is there a way to tell whether the script was ran via command line versus crontab?
I know that I can send a variable, like so:
# bash foo.sh bar
And then in the script, use:
if [ $1 -eq "bar" ]
then
# it was ran via command line
fi
but is that the best way?
The goal here would be to printf results to the screen if it's ran via command line, or email them if it's ran via crontab.

Running via cronjob, any way to check the server load and try again later if it's too high?
I'm writing a script that I'll run via cronjob at around 1am. It'll take about 15 minutes to complete, so I only want to do it if the server load is low.
This is where I am:
attempt=0
# server load is less than 3 and there have been less than 5 attempts
if (( $(awk '{ print $1; }' < /proc/loadavg) < 3 && $attempt < 5))
then
# do stuff
else
# server load is over 3, try again in an hour
let attempt++
fi
The question is, how do I get it to stop and try again in an hour without tying up server resources?
My original solution: create an empty text file and touch it upon completion, then the beginning of the script would look at the lastmodified time and stop if the time is less than 24 hours. Then set 5 separate cronjobs, knowing that 4 of them should fail every time.
Is there a better way?
