Re^3: Seperating individual lines of a file

First, that's an interesting use of push - you could just do @DATA=<ORIGFILE>;, but I don't think that's a big deal.

Second, you'll find that you'll want to open your file for writing by using the open, FILEHANDLE, ">filename" nomenclature.

Third, as written, your code will open a file called "host1 BUNCHOFDATAINALINE". You might want to split( /pattern/, expression ) each line of the file so you can separately refer to the separate pieces of data, like ( $HOSTNAME, $SOMEDATA ).

$/  =  q#(\w)#  ;  sub  sig { print scalar reverse  join  ' ',  @_  } 
+ sig
map { s$\$/\$/$\$2\$1$g && $_ } split( ' ', ",erckha rlPe erthnoa stJu

ok, on the split function, can i split $line into two sections, one being the first 16 characters, then name the file via this string of characters?	[reply]

If you're specifically interested in just the first 16 characters, you could also look into `substr( EXPR, OFFSET, LENGTH)`. When I saw "`host1 BUNCHOFDATAONALINE`" I assumed that splitting on whitespace was what you were looking for, but when you phrase it as "one being the first 16 characters", `substr` comes to mind. You may wish to examine the differences between split and substr to see which would suit you better. --chargrill `$/ = q#(\w)# ; sub sig { print scalar reverse join ' ', @_ } + sig map { s$\$/\$/$\$2\$1$g && $_ } split( ' ', ",erckha rlPe erthnoa stJu +" );` [download]	[reply] [d/l] [select]

Yes, you can, but then chances are that substr or unpack are better suited for the tast. Split works best for splitting on a pattern. Well, more precisely it is exactly for splitting on a pattern!
