Find Out My Linux Distribution Name and Version

Re-emerge all ebuilds with missing files (Gentoo Linux)
Revised approach to and3k's version, using pipes and read rather than command substitution. This does not require fiddling with IFS when paths have whitespace, and does not risk hitting command-line size limits. It's less verbose on the missing files, but it stops iterating at the first file that's missing, so it should be definitely faster. I expanded all the qlist options to be more self-describing.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Find files with lines that do not match a pattern
This one would be much faster, as it's only one executed command.

Sum file sizes
Even simpler! Use du ... the -s and -c flags summarize and print a grand total of all files recursively. The -b flag prints in byte format. You can use the -h flag instead to print in human readable format.

get total of inodes of root partition

Optimize Xsane PDFs
Xsane produces PDFs that are too large - particularly multipage PDFs. This command compresses them. If you do not use A4, remove the -sPAPERSIZE flag.

E-mail a traditional Berkeley mbox to another recipient as individual e-mails.

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

Show all LISTENing and open server connections, with port number and process name/pid
