you could try some "autoincrement" script
#!/bin/bash
# handles sub-directories in /backup, name format something like "sub_###"
with ### being a serial number
# get the last one
last=$(ls -1 /backup/sub* | sed -e s/^.*_// | sort -nr | head -n 1)
new=$(($last + 1))
mkdir /backup/sub_$new
cp -a /etc /backup/sub_$new

>I just wrote a bash script for making manual backups easier (I do them
manually when I'm about to edit something major) it basically makes a new
directory in /backup/ who's name is equal to today's date, then recursively
copies certain dirs I want backed up.

>The problem is, on some projects I like to do the manual backup each time
I get to a stable point before making the next few edits. What I'm wanting
is for the script to check and see if a directory with today's date already
exists. If it does I want it to append the hour as well as the date. Then
if there's already on with the same hour it should append the minute.

>Another option would be for it to add something like _1 to the end and
increment _1 by one digit each time (_2, _3, _4....) but I like the day,
then hour, then minute better. I guess we could add seconds for amusement's
sake.

>Anyway, I'm sure I could figure out how to do an if...else loop, I've seen
examples, but in bash I've never seen an example of checking for the
existence of a file or dir. Can anyone show me how to do that?
