[wplug] bash script for numbering filenames by date

[Poyner, Brandon]

Not very pretty, I'd probably do this in perl, but this will prepend the
file modification date to the file name.  Remove the echo to make it
really do the job.

for i in * ; do date=`stat -c '%y' $i | awk -F ' ' '{print $1}'` ; echo
mv $i $date'_'$i ; done

Subject: [wplug] bash script for numbering filenames by date


I have a little bash script (just a simple command line):
q=1; for i in *.jpg; do mv "$i" `echo $q"_"$i`; let q+=1; done;

This will add as a prefix a sequential number to the beginning of each
JPG
file in the current directory followed by an underscore.

Two problems that I'm not good enough in shell commands to conquer:

1) I'd like the numbers to begin at 001 (and follow 002,003,004) as in 
terms of alphabetcal order, 100 comes before 2, 3, 4, etc.

and

2) I'd like to number the files in terms of file dates and not file
names.  
I.e. currently the above command(s) number the files in order of their 
filenames whereas I'd like to do it based on the dates associated with 
them.

Any suggestions?
