Find filenames with three digits and add zeros to make five digits
Hello all! I've looked all over the internet and this site and have come up a loss with an easy way to make a bash script to do what I want to do. I have a file with a naming convention as follows:
2012-01-18 string of words here 123.jpg
2012-01-18 string of words here 1234.jpg
2012-01-18 string of words here 12345.jpg
What I am trying to do is search through all my files and folders within a directory and rename all the files so they have a five digit number instead of a three or four digit number with any empty space filled by a zero.
2012-01-18 string of words here 00123.jpg
2012-01-18 string of words here 01234.jpg
2012-01-18 string of words here 12345.jpg
As seen above, some files have three digits, some four, and some five. Is there any easy way to achieve this? I've been using the find command along with rename traversing folder by folder to change all my files into this format.
Any help would be greatly appreciated.

Hi I'm new to this. I need to cut off the last 10 digits from a line.
I've used awk {'print $4'} filename.txt | cut -c 32-42 but this does not guarantee only the last 10 characters.
Please help. Thanks.

I want to check the argument in KSH. If the user type in the prompt 'find 3' it will format 3 to 003 to match the data in the text file. Same as with 10 to 010. Always begins with 0.

Output:
003

Probably an easy one here but how do I get a sequence to get used as mentioned. For example in the following I want to automatically create files that have a 2 digit number at the end of their names:

rename - renames multiple files SYNOPSIS
rename [ -v ] [ -n ] [ -f ] perlexpr [ files ] DESCRIPTION
"rename" renames the filenames supplied according to the rule specified as the first argument. The perlexpr argument is a Perl expression which is expected to modify the $_ string in Perl for at least some of the filenames specified. If a given filename is not modified by the expression, it will not be renamed. If no filenames are given on the command line, filenames will be read via standard input. For example, to rename all files matching "*.bak" to strip the extension, you might say rename 's/.bak$//' *.bak To translate uppercase names to lower, you'd use rename 'y/A-Z/a-z/' * OPTIONS
-v, --verbose Verbose: print names of files successfully renamed. -n, --no-act No Action: show what files would have been renamed. -f, --force Force: overwrite existing files. ENVIRONMENT
No environment variables are used. AUTHOR

If you give an invalid Perl expression you'll get a syntax error. BUGS
The original "rename" did not check for the existence of target filenames, so had to be used with care. I hope I've fixed that (Robin Barker). perl v5.14.2 2014-09-26 RENAME(1)
