terminal commands to locate files

[and0rsk]

I'm really new to regex and I'm still trying to get the hand of complicated scripting. Goal is to locate every file with the words iTunes with it thats over 5 mb.

I was originally thinking of doing something like:

stat -c %s | locate iTunes | # this would get results over 5000000 bytes grep '[0-9][0-9]'

Obviously I'm not doing this right but I would appreciate some help on this.
Also any resources that are particularly good in understanding regex would be really appreciated.

Thanks

if your files are static then locate is ok

locate '[iI][tT]unes*' | while read f; i=$(stat -c %s "$f"); echo "$f: $i"; done | grep "5000000$"

if they've changed recently then use find instead

find /path/to/folder -iname '[iI][tT]unes*' -exec 'i=$(stat -c %s {}); if [ "$i" -gt 5000000 ]; then echo {}; fi' \;

you might want to check my work, I'm tired

one can force database refresh for locate with sudo updatedb

You don't need to pass the find output to stat, you can test the size as part of your find command e.g. if it is files whose name contains iTunes that you want to find (not clear from your original post)

find . -name '*iTunes*' -type f -size +5000000c

Note that -name only matches the file portion of the name - not the directory path. If that's not what you want then post back with more details of exactly what you are trying to achieve.
