The above script just removes spaces from any where in the line.
I like to trim each field in a comma seperated file.

I wrote the following code:
Code:
awk '{gsub("^[ ]*","",$1);gsub("^[ ]*","",$2) ;gsub("^[ ]*","",$3) print $1,$2,$3;}' filename > filename1
awk '{gsub("[ ]*$","",$1);gsub("[ ]*$","",$2) ;gsub("^[ ]*$","",$3) print $1,$2,$3;}'filename1 > filename

The problem with this code is it not versatile for different files with different number of fields.

Appreciate help on making this versatile
