Scripts written in Bash can also be debugged, just like Python,perl and other interpreted languages. Create a new script named Servinfo and add executable permissions:
Copy Code code as follows:
$ VI Servinfo
#!/bin/bash
echo "Hostname: $ (Hostname)"echo "Date: $ (date)"echo "Kernel: $ (Uname-mrs)"
$ chmod +x Servinfo
With Bash-x to debug the above script, bash prints each line of script first, then prints out the results of each line of script:
