bars (|) at fixed column positions in each record as a field separator.

Example -> 123456catdogbirdZYWUX
Becomes -> 123456|cat|dog|bird|ZYWUX

What is the simplest shell script for such a problem. Thanks

I don't know about the simplest, but awk could do it like:

awk '{print substr($0,1,6) "|" substr($0,7,3) "|" substr($0,10,3) "|" substr($0,13,4) "|" substr($0,17) }'

Or sed could do it like:

sed 's/$......$$...$$...$$....$$.....$/\1|\2|\3|\4|\5/'

In fact, there's no need to include the fifth expression: just add the
pipes after the first four and let the rest of the line remain unchanged.

It would be nice if there were a way to do it with cut, but I can't think
of a way to insert separators without echoing to a pipe to cut five times.
sed (as A. J. Harlow illustrated plus the slight change I recommended) is
better than five calls to cut.

I don't know if this is the simplest, but it's simple and it works:

echo 123456catdogbirdZYWUX | \
sed -e 's/$......$$...$$...$$....$/\1|\2|\3|\4|/'

-r
