parsing filename and grabbing specific string patterns
Hi guys...Wow I just composed a huge post and it got erased as I was logged out automatically
Anyways I hope someone can help me out here.
So the task I'm working on is like this
I have a bunch of files that I care about sitting in a directory say $HOME/files
Now my job is to go and loop over all these files and then grab parts of each filename and check if the parsed string exists in a parameter that is
passed to the script say $4
The filename parsing has the following rules
1: testfile_string1_string2_20100232to201130203.csv
parsed value should be "string1_string2"
2: testfile_string3_string4.csv
parsed value should be "string3_string4.csv"
3: testfile_string5_string6_string7_20113203to20110423.csv
parsed value should be "string5_string6_string7"
So the idea here is to grab the part of the filename after the first "_" upto a digit "20103232" eg 1 , eg3
Or the end of the string in case numeric values aren't there eg 2
I've been trying all day but I'm not able to find an answer for this
I'ld appreciate if one of you experts would help me out.
Thanks
