remove a string from a file in c

[Jumux]

Whats a good way to remove a string from a file?

[bwkaz]

sed -e 's/thestringtoremove//' <file >file.out

;)

Of course, you'll want to make sure that "thestringtoremove" only exists on one line; this will remove the first occurrence of it on every line it occurs in.

A common approach is to read the file you want to have lines/strings removed in and write the things you want to leave to a new file. When EOF is reached, you close both files, delete the original one and rename your new file to the name of the old one.

Its terrible style, but it works.
