trying to match yyyy-mm-dd what am I missing?

trying to match yyyy-mm-dd what am I missing?

[Timothy Luoma]

I am trying to match all folders in the CWD which are in the format  
YYYY-MM-DD.

Actually I'm just trying to match the ones from 2000 so I am using

2[0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]

as my regex.

This is my script:

for i in *
do

if [ -d "$i" ]
     then
         if [ "$i" = 2[0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9] ]
     then
         echo "YES: $i"
     else
         echo "no: $i"
     fi
fi

done

Here are the results:

YES: 2005-08-24/
no: 2005-08-26/
no: 2005-08-27/
no: 2005-08-28/
no: 2005-08-29/
no: access.log/


So it is only matching the first one, and I can't figure out why.

ps - actually I eventually want to match any file/folder that is NOT  
(a directory AND in yyyy-mm-dd format)

I don't know why it would match the first one, but if you have MARK_DIRS
set, that's going to fail.

Timothy Luoma <lists@tntluoma.com> typed:

:          if [ "$i" = 2[0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9] ]

This gets expanded to all the directories matching it.  See
"CONDITIONAL EXPRESSIONS:  ....
 Normal shell expansion is performed on the file, string and pattern
 arguments, but the result of each expansion is constrained to be a
 single word, similar to the effect of double quotes."

You're trying to match each against (in your case with MARK_DIRS set)
"2005-08-24/ 2005-08-26/ 2005-08-27/ 2005-08-28/ 2005-08-29/"

Try a different solution, e.g.:

for i in *(^M)
do

if [ -d "$i" ]; then
     case $i in
        2[0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]) echo "YES: $i";;
        *) echo "no: $i" ;;
     esac

fi

done

Hrm... that didn't work here:

$ for i in *(/); do [[ $i == 2[0-9][0-9][0-9]-[0-9][0-9]-[0-9] 
[0-9] ]] && print "$i YES" || print "$i NO"; done

2005-08-24/ NO
2005-08-26/ NO
2005-08-27/ NO
2005-08-28/ NO
2005-08-29/ NO
access.log/ NO

I could have read that 1,000 times and not understood that it applied  
to my situation.

Ah!  That works!  Thanks.


I am using this, together with the previous script about getting the  
creation date, to easily sort folders with lots of stuff in them into  
folders with contents organized by creation date.

Thanks!
