the 'replace' command

Got a file that has xxx.xxx.xx.xxx and want to replace it with yyy.yyy.yy.yyy?


shell> replace xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy -- myfile.txt

The "--" tells the replace command where the string replacements end and the file name starts.

Or you can pipe into it like so:

shell> replace xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy < myfile.txt

This will replace x with y in the myfile1.txt:

shell> replace x.x.x.x y.y.y.y y.y.y.y x.x.x.x -- myfile1.txt

This will actually swap the two in the two files:

shell> replace x y y x -- myfile1.txt myfile2.txt
