UNIX for Dummies Questions & Answers

Hi All,

I am facing issues converting white spaces and tabs together in a file I am reading. Here is the command I am trying:

Code:

tr -s ' '@ | sort -t@ +1n filename

I guess the problem is that it is not converting the tabs to another delimiter. Also, I am supposed to accomplish this only using tr command and no sed awk commands. Please help me out seniors !!

Info:

1 > I am sorting on the 1st column which is a numeric column.
2 > I am not supposed to create any temporary files to achieve the o/p.

Requesting everyone to help.

Regards,
sh_kk

Code:

cat filename | tr "\t" "@"

Its even supposed to sort !!!

And you are not considering the white spaces.

Please reply ... I urgently need a solution on this.

provide sample input....

Try:

Code:

tr -s '\t ' '@' < filename|sort -t@ +1n

Note that set1 contains both a " " and a "\t".
