Shell Programming and Scripting

Hi,

I'm trying to print and outrput of a timestamp from a script i did that calcs de time diference betwen 2 timestamps in the format HH:MM:SS and i properly formated it with printf inside awk, but i can't do it with separate statements.

This works fine, but can you explaim-me how to do it in a single statment?

Code:

echo "$E2H" | awk '{printf "%02d", $1}{printf ":"}'
echo "$E2M" | awk '{printf "%02d", $1}{printf ":"}'
echo "$MOD" | awk '{printf "%02d", $1}'

This dont work. I want a single statment inside awk or some other alternative way. Using korn88 shell in a standard unix awk, no gnu tools, it's HP-UX 11

Code:

echo "$E2H:$E2M:$MOD" | awk 'FS=":" {printf "%02d", $1}{printf ":"}{printf "%02d", $2}{printf ":"}{printf "%02d", $3}'

Cheers,

Please use code tags when posting data and code samples!

Code:

echo "$E2H:$E2M:$MOD" | awk -F: '{printf ("%02d:%02d:%02d\n", $1,$2,$3)}'
