How to insert tab at specified column.HELP

sslr · #1 (**permalink**) 09-20-2007

I have input like:
1234567890

cut -c1-3,6-7,9-10 input > output

Now I got 1236790.

I want to insert space between each cut. So the output like:
123 67 90

Can anybody help?
Thanks.

One way to add spaces (not a tab or "\t" character):

Code:

awk '{print substr($0,1,3), substr($0,6,2), substr($0, 9,2)  }' > output

Is there other way using other UNIX command? awk is not working for me.
giving me "16 bit MS-DOS Subsystem" error message.

This is one alternative using GNU cut:

Code:

#!/usr/bin/env sh

# @(#) s1       Demonstrate insertion of string for cut output fields.

set -o nounset
echo

## Use local command version for the commands in this demonstration.

echo "(Versions of codes used in this script -- local code \"version\")"
version bash cut

echo
echo " Expecting |123 67 90|"

echo "1234567890" |
cut -c1-3,6-7,9-10 --output-delimiter=" "

exit 0

Producing:

Code:

% ./s1

(Versions of codes used in this script -- local code "version")
GNU bash, version 2.05b.0(1)-release (i386-pc-linux-gnu)
cut (coreutils) 5.2.1

 Expecting |123 67 90|
123 67 90

See man pages for details ... cheers, drl

Thank you drl. You are so helpful.

What if two field being cut are next to each other, the delimiter will not be inserted?
cut -c1-3,4-5 --output-delimiter="|" input > output
The output will be:
12345

How to get 123|45?

Another question is how to get rid of the leading space, if I have input like:
1234567890
I'd like to have output
123|45
instead of
123|45

Could you please help?
Thanks.
