Check These Out

Show the command line of a process that use a specific port (ubuntu)

Pull git submodules in parallel using GNU parallel
Make sure to run this command in your git toplevel directory. Modify `-j4` as you like. You can also run any arbitrary command beside `git pull` in parallel on all of your git submodules.

Check general system error on AIX
Check general system error on AIX

List only hidden files
You can omit the -d to see what's inside directories. In that case, you may want -a to see dotfiles inside those directories. (Otherwise you don't need -a since you're explicitly looking at them.)

Plaintext credentials sniffing with tcpdump and grep
Simple TCPDUMP grepping for common unsafe protocols (HTTP, POP3, SMTP, FTP)

create ICO file with more than one image
requires imagemagick. -background transparent is of course optional.

File rotation without rename command
Rotates log files with "gz"-extension in a directory for 7 days and enumerates the number in file name. i.e.: logfile.1.gz > logfile.2.gz I needed this line due to the limitations on AIX Unix systems which do not ship with the rename command.

Remove newlines from output
?Cat and grep? You can use only grep ("grep \. filename"). Better option is awk.

Fast portscanner via Parallel

concatenate compressed and uncompressed logs
with zcat force option it's even simpler.
