I would like to copy the directory name, not path, to the IPTC:Caption-Abstract field of its contents.
When I run the following command:
exiftool '-iptc:caption-abstract<directory' /Users/steve/Desktop/School\ Photos/School\ Photos\ \(1\).jpg Exiftool copies the directory path to the IPTC:Caption-Abstract field of its contents, in this case "/Users/steve/Desktop/School Photos". How can I copy just the directory's name instead?
I've been reading the exiftool Application Documentation, and I found this information. Unfortunately, I'm having trouble deciphering it.
QuoteA substring of the original file name, directory or extension may be taken by specifying a field width immediately following the '%' character. If the width is negative, the substring is taken from the end. The substring position (characters to ignore at the start or end of the string) may be given by a second optional value after a decimal point. For example:
Input File Name Format Specifier Output File Name
---------------- ---------------- ----------------
Picture-123.jpg %7f.txt Picture.txt
Picture-123.jpg %-.4f.out Picture.out
Picture-123.jpg %7f.%-3f Picture.123
Picture-123a.jpg Meta%-3.1f.txt Meta123.txt
For %d, the field width/position specifiers may be applied to the directory levels instead of substring position by using a colon instead of a decimal point in the format specifier. For example:
Source Dir Format Result Notes
------------ ------ ---------- ------------------
pics/2012/02 %2:d pics/2012/ take top 2 levels
pics/2012/02 %-:1d pics/2012/ up one directory level
pics/2012/02 %:1d 2012/02/ ignore top level
pics/2012/02 %1:1d 2012/ take 1 level after top
/Users/phil %:2d phil/ ignore top 2 levels
(Note that the root directory counts as one level when an absolute path is used as in the last example above.)

Also, all of these folders are prefixed with a date. Is it possible to copy everything after the 17th character of a directory's name to the IPTC:Caption-Abstract field of its contents.
An example folder name is: "2004.06.09 - 1 - School Photos". I would like to move "School Photos" to the IPTC-caption-abstract field.
Thanks again Phil. I love your tool.

Hi Steve,
The %d, %f and %e apply only where a file name is expected, so they don't help here.
Instead, the alternative is to use the advanced formatting feature, which can be a bit tricky.
Here is a command that should take everything after the date in the directory:
exiftool '-caption-abstract<${directory;s/.*\d{4}-\d{2}-\d{2} \d+ //}' DIR
Notes:
1) the above quoting is for Mac/Linux. Use double quotes instead in Windows.
2) if the subsitution pattern doesn't match, then the full directory name will be written.
To learn more about substitution expression, Google "Perl regular expressions".

Phil,
Thanks for the help. I Googled "Perl regular expression substitutions" and found a wealth of information.
Until an hour ago, I knew absolutely nothing about Perl. Now, I know some--albeit very little--about Perl regular expressions and substitutions. What fun! Thanks for giving me the challenge.
Since I use periods to separate my date values, not hyphens, I had to change the code you gave me slightly. Here's what I came up with:
exiftool '-iptc:caption-abstract<${directory;s/.*\d{4}.\d{2}.\d{2} \- \d* *\-* *//}' '-comment<${directory;s/.*\d{4}.\d{2}.\d{2} \- \d* *\-* *//}' -overwrite_original FILE
It works like a charm.

The dot is a wildcard in regular expressions and matches any single character. In the places you want it to exactly match a dot, you'll want to put a backslash before it (
\.). For example, use
${directory;s/.*\d{4}\.\d{2}\.\d{2} \- \d* *\-* *//}.
