copy ACL of one file to another using getfacl and setfacl
If you copy windows file in e.g. cygwin the ACL might miss on the copied file. With this command you can copy the ACL of an existing file to another. WARNING: Existing ACL will get lost.

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"

Detect if we are running on a VMware virtual machine
If you run this command on a VMWare Virtual Machine, it will return the string "VMware Virtual Platform". If you run it on a physical machine, it will return nothing. Useful for having a script determine if it's running on a VM or not. Of course, you must have dmidecode installed for this to work. Try it this way in a script: ISVM=$(dmidecode | awk '/VMware Virtual Platform/ {print $3,$4,$5}') Then test if $ISVM has text in it, or is blank.

Rename all .jpeg and .JPG files to .jpg

Convert JSON to YAML (unicode safe)
If you tried the other Python version of Convert JSON to YAML and you end up with lines that has "!!python/unicode", this version of the command is for you.

find previously entered commands
Searches bash-history in reverse order (last entered commands first). Pressing ctrl+r again shows the next matching entry.

Use lynx to run repeating website actions
This command will tell lynx to read keystrokes from the specified file - which can be used in a cronjob to auto-login on websites that give you points for logging in once a day *cough cough* (which is why I used -accept_all_cookies). For creating your keystroke file, use: $ lynx -cmd_log yourfile

Find the package that installed a command

Realtime lines per second in a log file
Using tail to follow and standard perl to count and print the lps when lines are written to the logfile.

Find default gateway (proper at ppp connections too)
