Why those left characters are seeing in this file and how can view it neatly.please any one suggest me wht to do.

thank you

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:

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

Or

# 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.

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:

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.

Thanks to both of you. actually
here what i tried is :

sed -e 's/^\[23\;80H \[24\;1H//;/^$/d;G' /home/file.log

reponse:

invalid command name "sed"
    while executing
"sed -e 's/^\[23\;80H \[24\;1H//"
    (file "READ.exp" line 3)

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

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

Thank you so much for the answer. Actually all i have tried but i dont fine any solution iam not able to remove those characters. I am using expect language and if any other options please let me know and it is really appreciable.
