Quick help on space padding - UNIX for Dummies Questions & Answers

Lokesha · #1 01-08-2008

Hi all,

I need to create a header record of width 121 charecter with below fields,
position 001-001 - 0
position 002-15 - filled with space
position 016-020 - date value
position 021-121 - filled with space

Iam using the below code:

echo 0"14 spaces"$date"100 spaces" >> output.txt

But I dont think this is correct approach. Could any one please correct me if Iam wrong?

With Regards / Lokesha R

check the printf command
eg

Code:

# printf "%05d" 13
00013

printf should do it

Code:

printf "%-15d%5s%100s\n" 0 "$date_here"
