Top Forums UNIX for Dummies Questions & Answers Trim String in 3rd Column in Tab Delimited File...SED/PERL/AWK? Post 302241260 by Franklin52 on Monday 29th of September 2008 02:35:02 AM

I disn't assume that you have spaces in the fields. This should work with spaces in fields:

Code:
awk 'BEGIN{FS=OFS="\t"}NR==1{print;next}{$3=substr($3,4)}1' file > newfile
