Top Forums Shell Programming and Scripting Request for advise on how to remove control characters in a UNIX file extracted from top command Post 302850149 by Skrynesaver on Wednesday 4th of September 2013 03:52:31 AM

Code:
 perl -pne 's/^[\[\d*m//g' file

Note the ^[ is a literal escape entered by hitting [CTRL]-V and then escape

On a side note top -b -n3 will run top 3 times with no control characters (mnemonic b for "batch" mode)
