The tab (^I) characters is represented in Perl strings via \t. Thus `@parts = split "\t", $string;` will separate tab-delimited parts.	[reply] [d/l]

split with '\t' has helped me. Thank you very much.	[reply]

`perl -le '$_="a\tb\tc";print join( "\n", split( /\t/ ) )'` If you've got a literal `^` followed by a literal `I` (i.e. you don't mean a TAB character), keep in mind that `split` takes a regex and `^` has a special meaning therein. If you're trying to parse something like a CSV file exported from Excel or the like, consider Text::CSV_XS.	[reply] [d/l] [select]

UPDATE: Doh! See dws's reply above. Damn sans-serif font... Examining the split documentation very closely we see that the first argument is in fact a regular expression. So you are trying to match a pipe at the beginning of the line. You need to escape your sequence. This could easily have been found by RTFM, and perhaps by a search BUT, it is something that even experienced people get nicked by. Enjoy. `-- perl -pew "s/\b;([mnst])/'$1/g"`	[reply]
