Lightbulb Filename timestamp
Hi Gurus,

I have different files with different timestamp and different base file name, I have to group those files based on basename and provide a unique file name for similar file names.

My Directory has following files.
Code:
abc_filename_20130623:00:09:00.txt
abc_filename_20130522:12:09:00.txt
czdfilename_20130623:00:09:00.txt
czdfilename_20130612:13:09:00.txt
xyz_23Jun2013:00:09:00_file.txt
xyz_22May2013:18:09:00_file.txt
yze_filee_20132306:00:09:00.txt
yze_filee_20122202:11:09:00.txt
......

Here I have different files with above format only time stamp is changed.

Now i need to group those files based on name, output should be

Output print:
Code:
abc_filename.txt
czdfilename.txt
xyz_file.txt
yze_filee.txt


Thanks in advance for your help gurus.

Code:
sed 's/_[0-9].*_/_/;s/_[0-9].*\./\./' file | sort | uniq

OR
Code:
awk '{sub(/_[0-9].*_/,"_");sub(/_[0-9].*\./,/\./);!A[$0]++}END{for(k in A) print k}' file
