Top Forums UNIX for Beginners Questions & Answers Need to find and replace in a file Post 302997764 by RudiC on Friday 19th of May 2017 06:14:41 AM

That specification is not too consistent: It's not clear if any ABC pattern should be matched, or just the one at positions 6 - 8. There's no 120th char position in the input sample, and esp. not 30 onwards. The replacement as well is not 30 char but 10 chars long. Will it always be the rest of the line to be replaced?
To simulate your sample output, try (GNU sed)
Code:
sed '/ABC/ s/./ /94g' file
