Jamie Landeg-Jones <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #2 from Jamie Landeg-Jones <[email protected]> --- Hi. Thanks for the reply. I'll explain how I got here: I wanted to do a quick hack to split a line at every character, and at that point, I was not familiar with "awk" allowing a null character to do the job. Hence, believing the strings was a regular expression, I set FS to "." which - contrary to the manual - was taken as a literal, not a RE! Indeed, in your description of the atom from re_format, you missed out: "or a single character with no other significance (matching that character)." As in your examples: You used examples where a single character is already a literal character in RE, which isn't always the case: % printf 'hello(world' | egrep '(' egrep: Unmatched ( or \( % printf 'hello(world' | awk -F '(' '{print $1}' hello I know this is hardly a major error, but it is still inaccurate - especially in the case of "."! Just for info, the actual text from gawk (which probably phrases it better than I did!) is: "If FS is a single character, fields are separated by that character. If FS is the null string, then each individual character becomes a separate field. Otherwise, FS is expected to be a full regular expression."
