RE: cat infile | translate all occurences of "NOT NULL" to ""

in vi you can type : and then 1,$s/oldstring/newstring/g
where 1 means start from the first line, $ means until the end of the file,
oldstring is what you want to replace, newstring is what you want to replace
it with, and the g means do it globally throughout the file.

e.g. 1,$s/NOT NULL//g should work

Hope this helps

Subject: [NOVICE] cat infile | translate all occurences of "NOT NULL" to
""

what command do I use to substitute all occurences of a certain string (say,
"NOT NULL") with another arbitrary string, (e.g. "")? I've tried grep and
tr, but can't figure it out.

Thanks,
