Hi vanid,

I understand you want to remove the set of characters [23;80H [24;1H at the beginning of some lines.

If so, try with:
Code:
# Removing only set of characters, without affect resulting blank lines 
sed 's/^\[23\;80H \[24\;1H//' inputfile

Or
Code:
# Removing set of characters, setting up double spacing in the output
sed -e 's/^\[23\;80H \[24\;1H//;/^$/d;G' inputfile

Hope it helps.

Regards.

log file problem
I tried it but when writing for expect we need to provide "exec" cmd before this sed command right? if do so its not working here what iam doing:
Code:
exec sed {-e s/^\[23\;80H \[24\;1H//} /home/files/logfile.txt

Try as is given by cgkmal in post# 2, except replace the inputfile with your orginal file name.

@scottn, think you're fighting a losing battle there...Smilie
@vanid, if you don't have sed, you probably don't have awk, but:

Code:
awk -F"1H" '!/\[23/{print $0};/\[23/{print $2}' /home/file.log
