Breaking apart a variable 1

[jestrada101]

What would be the best method to break apart a variable?

For example:
$> breakapart.ksh /export/home/user/myfile.txt


I want to be able to separate the directory structure from the filename. The directory structure can change, so it's not always going to be /export/home/user/

Thanks for any guidance.

Try something like this:

myPathName="/export/home/user/myfile.txt"
echo "dirname=`dirname $myPathName`"
echo "filename=`basename $myPathName`"

If you're in ksh, you can do this:

echo "dirname=${myPathName%/*}"
echo "filename=${myPathName##*/"

Hope This Help

This is what I need.. but, if a directory is not specified for the directory, it'll show me the filename as the directory, is there a way to make it null or send some other value other than the filename:

myPathName="myfile.txt"
echo "dirname=${myPathName%/*}"
echo "filename=${myPathName##*/"

Thanks

Hi,

You can user 'dirname ' and 'basename' commands :

myPathName="myfile.txt"
echo "dirname=$(dirname "$myPathName&quot" # -> .
echo "filename=$(basename "$myPathName&quot" # -> myfile.txt

Have I missed the point ?
myPathName="/export/home/user/myfile.txt"
filename=$(basename $myPathName)

filename should then contain only 'myfile.txt'

Use the first suggestion...
[tt]
% echo "dirname=$(dirname $myPathName)"
dirname=.[/tt]

Thanks all.. I guess there wouldn't be a method to get null. I think this will work. Thanks again!
