howto remove a particular phrase from a text file?
 

i need to remove a little piece of text from a bigger text file. i can find the phrase with grep, but have no idea howto remove it from the file.

any advice appreciated.

Hi,

Sed can do that:

sed -i 's/to be removed//' infile

The above will remove to be removed from the infile and saves it in place (the i- option). Try without the -i option first, output is printed to screen instead.

Hope this helps.

could be done with grep,

Hi,

True, grep can also remove, but it takes out the whole line, not a part of that line. Depending on what you want, both can be used.

BTW: Use: grep -v "[phrase]" infile > outfile if the grep statement is preferable, it's more resource friendly (only one command instead of 2).

This solves the issue. Thank you very much :)
