UNIX for Dummies Questions & Answers

Hi ,

I am trying to write a shell script which will validate all .csv file names in a directory , my file name format is as below.

CDR_SCAN_Report_YYYYMMDDHHMI.csv

1. I need to validate the name should start with CDR_SCAN_Report.
2. And the time stamp part is a valid time stamp,if it is not valid the script should throw an error

Code:

$cat > filenamevalidation.sh
#!/bin/ksh

if [[ (${file_name} = @(CDR_SCAN_REPORT([0-9]))  -- here I am not sure how to validate the date part.

can any one give me some logic how can I validate the timestamp part of the file name.

regards,shruthi

What does the "I" mean?

This will show the names that does not comply with the format:

Code:

find . -maxdepth 1 ! -regex '.*CDR_SCAN.*_[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]\.csv.*' -print

There is a flaw however in that regex as it does not really validates that the filename contains a valid date, so it would also match filenames like 'CDR_SCAN_Report_201140596799.csv'

Not sure if you also need real date validation. (?).
