UNIX for Dummies Questions & Answers

Try the following command
The above code works, however, the formatting may not be good.
I have still corrected the code for your future references.
Franklin52's code works perfect

Hi All,

I was being foolish. Ygor's command works fine, the file I was testing on with numbers was separated by spaces rather than tabs (My Bad!).

I still can't get the cut command to work. If I try bobbygsk's suggestion:

Code:

cut -d" " -f1,6 file1 > file2

then it prints out the whole file rather than columns 1 and 6.

Also, another question. Let's say before I issue the awk command to display columns. I use the grep command to remove commented lines. Is there a way I can run both commands at the same time as opposed to saving a new file at each step as in this example:

Code:

$grep -h -v [#,*] alpha.txt > test.txt
$cat test.txt
a       b       c       d
a       b       c       d
a       b       c       d
a       b       c       d
a       b       c       d

$awk 'BEGIN{FS=OFS="\t"}{print $1,$3}' test.txt > final.txt
$cat final.txt
a       c
a       c
a       c
a       c
a       c
