Check These Out

grep (or anything else) many files with multiprocessor power
xargs -P N spawns up to N worker processes. -n 40 means each grep command gets up to 40 file names each on the command line.

Clone all repos from a user with lynx
https://wuseman.github.io/wcloner/

list files recursively by size

Create a 5 MB blank file via a seek hole
Similar to the original, but is much faster since it only needs to write the last byte as zero. A diff on testfile and testfile.seek will return that they are the same.

Encode/Decode text to/from Base64 on a Mac w/out Mac Ports
I have a mac, and do not want to install mac ports to get the base64 binary. Using openssl will do the trick just fine. Note, to decode base64, specify a '-d' after 'base64' in the command. Note also the files base64.decoded.txt and base64.encoded.txt are text files.

execute your commands and avoid history records
$ secret_command;export HISTCONTROL= This will make "secret_command" not appear in "history" list.

Rename files in batch

Function to split a string into an array
It works as a method applicated to a variable, converts the string variable into an array

Detach a process from the current shell
Continue to execute the command in background even though quitting the shell.

List all installed PERL modules by CPAN
This command will give you the detailed information about the installed perl modules i.e. installed path, Link type, version, files etc.
