Help: file_grep()

Showing help on 'file_grep()'

Function: LIST file_grep(FHANDLE fh, STR search [,?match_all = 0])

Search for a string in a file.

Assume we have a file `test.txt` with the contents:

asdf asdf 11
11
112

And we have an open file handle from running:

;file_open("test.txt", "r-tn")

If we were to execute a file grep:

;file_grep(1, "11")

We would get the first result:

{{"asdf asdf 11", 1}}

The resulting LIST is of the form {{STR match, INT line-number}}

If you pass in the optional third argument

;file_grep(1, "11", 1)

we will receive all the matching results:

{{"asdf asdf 11", 1}, {"11", 2}, {"112", 3}}
