To Create and Bash Script On Linux Mint

Introduction:

It is convention to give files that are Bash scripts an extension of .sh (myscript.sh for example). As you would be aware Linux is an extensionless system so a script doesn't necessarily have to have this characteristic in order to work.

Installation procedure :

Step 1 : To Check the os version

root@linuxhelp:~# lsb_release -a
No LSB modules are available.
Distributor ID:	Linuxmint
Description:	Linux Mint 20.2
Release:	20.2
Codename:	uma

Step 2 : Creating the touch file by uding the following command

root@linuxhelp:~# touch testscript.sh

Step 3 : Changing the permission to the below file

root@linuxhelp:~# chmod 755 testscript.sh

Step 4 : Long list the file by using the following command

root@linuxhelp:~# ls -la
total 49784

drwxr-xr-x 19 root root     4096 Jan  4 09:07 ..
-rw-------  1 root root     4467 Jan  6 06:03 .bash_history

drwxr-xr-x  3 root root     4096 Jan  5 04:28 .local
-rw-r--r--  1 root root      161 Dec  5  2019 .profile
-rw-r--r--  1 root root 50916586 Sep 30 02:59 rstudio-server-2021.09.0-351-amd64.deb
-rwxr-xr-x  1 root root        0 Jan  6 06:32 testscript.sh
-rw-r--r--  1 root root      168 Jan  6 04:35 .wget-hsts

Step 5 : Editing the testscript.sh file

root@linuxhelp:~# nano testscript.sh 
#!/bin/bash
echo bash script is started
ping -c 7 192.168.6.180
ls –la
echo bash script completed

Step 6 : Running the testscript.sh by using the following command

root@linuxhelp:~# ./testscript.sh
bash script is started
