I wanted to use the sort utility with the -t option to specify tab separators, but

sort -t "\t"

doesn't work.

  • Why won't '\011' work? Tried it on my Linux box and for some reason it doen't work.

  • I tried \t and it doesn't work, neither does \n, Is there a csh switch to turn off escaped characters? If there is, I've never heard of it.

Don't use double quotes.

sort -t $'\t'

Or I think Ctrl V inserts a Tab??

    @RedGrittyBrick Tab completes.

    Control-V alone won't work; Control-V + Tab will. I like the $'...' trick, though; now I've learned something new. :-)

  • I've always learned it as $' '. It allows you to enter a string, but also have escaped characters. Double quoting literally prints \t If you leave off the quotes you get a tab character.

Try Control-v, then Tab. If you see the cursor tab over to the right, it worked.

According to the comment by Mark you can also try Control-v and then Control-i.

    When I do this, I get a real tab (i.e. indentation).

    Oops. You're right. But it is entering the tab character, not doing command-line completion (which is what bash normally does with a tab). I tried sort -t " " (with the literal tab as described above) and it worked for me.

  • Yep, that's what I meant by indentation. Didn't know a better term.

    Ctrl-v, Ctrl-i will also work (I found this answer here). Also, I think a Ctrl-q, Ctrl-v, Tab will work. Thanks L2G!

  • BTW, I would love to accept both answers, but since I think surfasb's solution is more readable, I accepted hers. I like yours, too, though, so voted it up. Thanks!

To put tab:

  • First press Ctr + v and

  • Then press tab key.

You can also use printf:

sort -t "$(printf "\t")"

Not like $'\t', printf use double quotes which allow you to use environment variables, like below:

char="\t" # any source just plain text

sort -t "$(printf "$char")"

Single quote is static and not flexible, though it's simple, you can choose based on your requirement.
