Bash

Sometime you need to know what’s your file encoding? Is it UTF-8, ISO 8859-1, ASCII or Windows 1252? You can find this out by using the file Unix command. Linux: file -i <filename> Mac OSX: file -I <filename> Example usage: username@server ~$ file -i somefile.php somefile.php: text/x-php; charset=us-ascii username@server ~$ file -i myutf8file.txt myutf8file.txt: text/plain; charset=utf-8 username@server ~$ file -i username.tar.bz2 username.tar.bz2: application/x-bzip2; charset=binary username@server ~$ If you want only the encoding....

I made a bash script listing all main domains and addon domains (for certain user by username or domain or for all users) in cPanel. Usage: lsdom [OPTION] [INPUT] Example: lsdom [cPanel username] Lists domains for certain user by username or domain or for all users Options: -d [domain] Displays all domains of the user of the input domain. -a, --all Lists all domains. -v, --version Displays version. -h, --help This help page....

I made a bash script listing all non-self-signed certificates (for certain user by username or domain or for all users) in cPanel.

There are at least three fun ways to echo multiline to a file. We are going to look at doing the output twice, the heredoc -method and writing multiline using double quotes. 1. Output twice I think this is the simplest and most intuitive method if you are familiar with linux output redirection. user@server:~/projects/blog\_content$ echo "This file is" >> multiline.txt user@server:~/projects/blog\_content$ echo "multiline" >> multiline.txt user@server:~/projects/blog\_content$ cat multiline.txt This file is multiline 2....

Sometimes when bash scripting you might want the ability to cancel your script’s loop with CTRL-C. Below is an exampl simple script which loops through a file of domains separated by line break and it digs the A record (IP address) of the domain. Read further to learn how to force quit this script. #!/bin/bash while read p; do dig $p A +short done <listofdomains.txt If your list of domains is large your and you want to quit this script, you cant....

This is something you need to do often for one reason or another. Maybe you have a bunch of text files, which have been named horribly and you have no idea which file has the thing you are looking for, but you happen to remember a word in that file. Or maybe you need to find which file contains a certain variable to find the root cause of an error you are experiencing in your script....
