I'm having a problem with a Shell Script.
In a nutshell I want to print the "$2" column of the file "$1" in my script "showColumn"
So, what I've tried:
#!/bin/bash
awk '{print $($2)}' $1
exit 0
Ok, I know that $($2) is totally incorrect, but you can see what I'm trying to do.
So what I want when I write "./showColumn file.txt 2" is printing the second column of file.txt but I don't know how to solve that.
Try:
#!/bin/bash
awk -v column="$2" '{print $column}' "$1"
exit 0
