UNIX for Dummies Questions & Answers

Newby here.....

Is there any way of doing a find & replace within a huge file other than using something like : " vi - FileForReplacing < /u1/excel/consultants "
contents of consultants file looks like
:1,$s/0000031/CON/g
:1,$s/0001032/JONES/g
:1,$s/0001355/SMITH/g
:1,$s/0002095/ARMSTRONG/g....etc! etc! etc!

the consultants file is quite large and this make the script run for sometime before it finishes

You could use sed.

Code:

sed -e 's/0000031/CON/g' -e 's/0001032/JONES/g' ... FilebeforeReplacing > FileafterReplacing

vino

thanks but if i were to use this method the command line would stretch for ever and ever

True.

Write the whole sed command in your /u1/excel/consultants with required modifications.

Again, you might need to write some other script to replace all your

:1,$s/0000031/CON/g

with

the sed -e thing.
