How To Create and Run Bash Script on Debian 11.3
To Create And Run Bash Script On Debian 11.3
Introduction
Bash is an acronym for “Bourne-Again Shell”. It is also used as a command-line interpreter for both UNIX and Linux. The BASH script also contains a series of commands that will later be executed while running the script. The bash script should also be commenced as #!/bin/bash.
Step 1 : Check whether the Debian OS version is installed by using the below command
linuxhelp@linuxhelp:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 11 (bullseye)
Release: 11
Codename: bullseye
Step 2: Log in as root user by using the below command
linuxhelp@linuxhelp:~$ sudo -s
[sudo] password for linuxhelp:
Step 3: Create file named testscript.sh by using the below command
root@linuxhelp:~# touch testscript.sh
Step 4: Long listing the files by using the below command
root@linuxhelp:~# ls -la
total 32
drwx------ 4 root root 4096 Sep 30 08:51 .
drwxr-xr-x 20 root root 4096 Sep 8 16:50 ..
-rw------- 1 root root 1991 Sep 30 08:47 .bash_history
-rw-r--r-- 1 root root 3106 Aug 15 2019 .bashrc
drwx------ 2 root root 4096 Apr 20 16:20 .cache
rw-r--r-- 1 root root 161 Sep 16 2020 .profile
drwxr-xr-x 3 root root 4096 Sep 8 17:00 snap
-rwr-r-- 1 root root 0 Sep 30 08:51 testscript.sh
-rw-r--r-- 1 root root 17 Sep 27 12:51 .vimrc
Step 5: Assign Permission to test script.sh file by using the below command
root@linuxhelp:~# chmod 755 testscript.sh
Step 6: Long listing the files by using the below command
root@linuxhelp:~# ls -la
total 32
drwx------ 4 root root 4096 Sep 30 08:51 .
drwxr-xr-x 20 root root 4096 Sep 8 16:50 ..
-rw------- 1 root root 1991 Sep 30 08:47 .bash_history
-rw-r--r-- 1 root root 3106 Aug 15 2019 .bashrc
drwx------ 2 root root 4096 Apr 20 16:20 .cache
-rw-r--r-- 1 root root 161 Sep 16 2020 .profile
drwxr-xr-x 3 root root 4096 Sep 8 17:00 snap
-rwxr-xr-x 1 root root 0 Sep 30 08:51 testscript.sh
-rw-r--r-- 1 root root 17 Sep 27 12:51 .vimrc
Step 7: Editing the testscript.sh file by using the below command
root@linuxhelp:~# nano testscript.sh
#! /bin/bash
echo “hello $LOGNAME
echo “welcome to the world of `hostname`
echo “the host name is `hostname`
echo “your present working directory is `pwd`
echo “thank you, $LOGNAME”
ping 127.0.0.1
Step 8: Run the testscript.sh by using the below command
root@linuxhelp:~# sh.testscript.sh
