Hi Team,
I have a file having size greater than 1 GB. What i want to do is to check if it contains any JUNK character (ie any special charater thats not on the key board stroke). This file has 532 column & seperated with ^~^.
I have found some solution from the file, but it is for a specific junk character not for all.
Can someone help me...
check if this helps:
grep -v '[A-Za-z0-9]' filename
Hi Yogesh,
No it is not working. In my file i have found one of the special character "�". But ur command is not showing it.
He means:
grep '[^[:print:]]' filename
I typically use this:
sed -e 's/[^ -~]//g' file_in > file_out
This removes all junk characters. not all lines with junk --- just all junk characters.
To tell if a file has junk . .. .
grep -c '[^ -~]' file_in
