easily strace all your apache processes
This version also attaches to new processes forked by the parent apache process. That way you can trace all current and *future* apache processes.

list files recursively by size

sort list of email addresses by domain.tld
email random list can be created here: https://www.randomlists.com/email-addresses

Invert selection with find.

Set file access control lists
The file myfile is owned by tom and has read and write permissions for tom. Group and other permissions are empty which make myfile readable and writable only by tom. setfacl enables user tom to give read permission to user john only. The command 'ls -l' shows a '+' sign telling us that file access control list has been setup for myfile.

Archive a directory with datestamp on filename
A useful bash function: gztardir() { if [ $# -ne 1 ] ; then echo "incorrect arguments: should be gztardir " else tar zcvf "${1%/}-$(date +%Y%m%d-%H%M).tar.gz" "$1" fi }

run complex remote shell cmds over ssh, without escaping quotes
Much simpler method. More portable version: ssh host -l user "`cat cmd.txt`"

search user defined function in c language

ls only directories
Like normal ls, but only lists directories. Can be used with -l to get more details (ls -lad */)

List folders containing only PNGs
