Find files that do not match specific patterns
Hi all,

I have been searching online to find the answer for getting a list of files that do not match certain criteria but have been unsuccessful.

I have a directory that has many jpg files. What I need to do is get a list of the files that do not match both of the following patterns (I have used the ? to act as any single character-in my case these are stricly numbers):

???-??-????.jpp AND ???-??-????-?mi.jpg

I would like to output the result to a text file.

Once I have this list it would be very helpful if anyone could propose an easy way to rename the files that to not match this pattern.

many thanks

Not too elegant, but this perl example should print a list of files that don't match your patterns:

Code:
#!/usr/local/bin/perl

$\ = "\n";

@files = split/\n/,`ls /path/to/your/dir`;
foreach (@files) {
  if (!/^...-..-....\.jpp|^...-..-....-.mi\.jpg/) {
    print;
  }
}

Thanks for that - but I don't seem to have perl on the hosted server I am using - any other suggestions?

Try this

Code:
#!/bin/sh

for file in `ls /path/to/yourdir`; do
  if [ -z `"echo $file | egrep '^...-..-....\.jpp|^...-..-....-.mi\.jpg'"` ]; then
    echo $file
  fi
done

excuse my ignorance - but I presume I would have to pass your code into a file and then execute it - how would I go about doing this?

replace "/path/to/yourdir" with whatever it should be and copy the script to clipboard

Code:
cat > script

paste content of clipboard and hit ctrl-d

Code:
chmod 755 script

and then run the script

Code:
./script

when I execute the script I get: ./script: line 7: syntax error near unexpected token 'fi'
