hi every one,

in the code am writing i have to check a file ids that are in an array.
my code is:

@accession_id = grep/\@array/ , topo_ids.srs;

it showed no error. but can't get the @accession_id printed.


@arrays contain list of ids that i have to look for in topo_ids.srs. Should I have to add 'g' to make that global


If you want to match all the elements in a list via a regular expression, you need to make up an appropriate regulare expression.  Hard to explain so I'll give you an example:

Code:

@indeed = ("cat","dog","bunny"); @source = (   "We have a cat\n",   "My son has cows in his garden\n",   "My daughter had a hamster\n",   "Hugh has a bunny at his place\n"); # Make up the regular expression to look for $filter = join('|',@indeed); @matched = grep(/$filter/,@source); print @matched;

Which runs:
Code:

earth-wind-and-fire:~/jun07/ox grahamellis$ perl hte We have a cat Hugh has a bunny at his place earth-wind-and-fire:~/jun07/ox
