Top Forums Shell Programming and Scripting 4 column tsv file, output 1 specific column Post 302257592 by casphar on Wednesday 12th of November 2008 03:04:41 PM

Thanks, the tr and cut command seems to be doing the trick. I did notice a few results missed the correct entry but this may be due to bad formating in the tsv file?

thanks

18      Jan 2   Linda   laugh
11      Nov 3   Vets    march

> cat file66c.tsv | tr "\t" "~" | cut -d"~" -f2
Oct 1
Jan 2
Nov 3

> cat file66c.tsv | awk '{print $2}'
Oct

Nov
