use sed / perl - that should be quite easier if you are not able to edit the file in place


could you post some examples on what need to be done ? Smilie

Thanks for your reply.

When am using sed, the command is not replacing the string.
sed -e 's/notes2/notes/g' expoutnotesall > outfile
I used ed in HOME argument format also in scrip as

ed $1 <<-EOT
1,\$s/notes2/notes/g
w
q
EOT


Can u tell me exactly how to use sed /perl here in shell scripts.

sorry, i cant give the contnent of input file.
This file contains the string "notes2" which has to be replaced by the string "notes".

Since i was not able to open in vi editor, i cant give the input file.
It is an export file produced by some command in our application which is in data file format. Using cat command i was able to view the file content.

Use fold command to cut the text in your file into multiple lines with 80 characters per line
Code:
fold -80 filename
