Running Sed on a file.

Shell Programming and Scripting
1

I'm taking in an arguement thats sorted in $file.

The $file contains a file name like file1.txt or something all files are in the same directory as the script..

Can I run sed on the file ? I was thinking of using something like

more file.txt | sed "s/http//"

Something like that is there a way to output the contents of the file and pipe it into sed ?

Thanks.

sed 's/http//' "${file}"

You don't need more. Just append the names of one or more files after the command:

sed "s/http//" file.txt file2.txt file3.txt
