Join lines and separate with spaces
Read vmargs.txt, which is a text file that could either be DOS-style (\r\n) or UNIX-style (\n) line endings and join the lines with a space separator. Can this be shortened/made more elegant?

Solaris get PID socket
Command line to get which PID is opening a socket on IP and PORT. Only useful under Solaris.

Set laptop display brightness
Run as root. Path may vary depending on laptop model and video card (this was tested on an Acer laptop with ATI HD3200 video). $ cat /proc/acpi/video/VGA/LCD/brightness to discover the possible values for your display.

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

for ssh uptime
This will run them at the same time and timeout for each host in ten seconds. Also, mussh will append the ip addres to the beginning of the output so you know which host resonded with which time. The use of the sequence expression {1..50} is not specific to mussh. The `seq ...` works, but is less efficient.

List the libraries used by an application
For example, you need to make a copy of all the libraries that a certain application uses, with this command you can list and copy them.

truncate deleted files from lsof
While the posted solution works, I'm a bit uneasy about the "%d" part. This would be hyper-correct approach: $ lsof|gawk '$4~/txt/{next};/REG.*\(deleted\)$/{sub(/.$/,"",$4);printf ">/proc/%s/fd/%s\n", $2,$4}' Oh, and you gotta pipe the result to sh if you want it to actually trim the files. ;) Btw, this approach also removes false negatives (OP's command skips any deleted files with "txt" in their name).

Install pip with Proxy
Installs pip packages defining a proxy

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

Binary clock
Like 7171, but fixed typo, uses fewer variables, and even more cryptic!
