Shell scripting pros

herve2001 · 02-24-2005, 01:59 PM

I'm looking for some help from anyone who knows shell scripting, I'm trying to do the following:

1-Accept a string form the terminal and use case to echo a suitable message if the string doesn't have at least 10 characters.

and

2-Write a script that displays, in head-style, the last three lines of each file in the current directory, duly preceded by the filename.

Thanks.

1)

Code:

#!/bin/bash

if [ `echo -n $1|wc -m` -lt 10 ];then
 echo Less than 10 chars.
fi

2) tail -vn 3 *
