perl

File name matching with -e and regular expressions

I need to check for the existence of a file in a directory. The file name has a pattern like:

/d1/d2/d3/abcd_12345_67890.dat

In my program, I will know the file name up to abcd_

I need to write an if condition using -e option and find the files matching above given pattern.

Solution

  • You can use glob to return a list of existing files whose name matches a pattern:

    my @files = glob '/d1/d2/d3/abcd_*.dat';

    In this case, there is no need to perform the -e filetest.
