sed? -- making substitutions

scabies · 12-21-2003, 11:10 PM

hello,

i want to add better titles to around 600 html files; i'd like to use sed because it seems the simplest way to do it. basically, i run the command

s/<title>/<title>Niles Register /gp

which prints out that substitutions are "successful", but the actual files aren't modified.

anyone know what i'm doing wrong? or should i use perl instead? this seems like a simple thing to get to work.

thanks in advance!

The problem you are experiencing is that sed is
a STREAM editor, not a file editor. All you need
to do is
sed <command mumble> -f file > file2
mv file2 file
