Stringing Multiple commands together in KSH
I am trying to to this
Code:
findCDZfile=`ls -at `find /opt/apps/busobj/bobj/bobje/data/ -name CDZ*.tmp``

and it doesn't seem to like me - is there a special escape character I need to use?

Hi.

I would stop using backquotes and use the $( ... ) notation, which is both easily nested, and readable.

Code:
findCDZfile=$(ls -at $(find /opt/apps/busobj/bobj/bobje/data/ -name CDZ*.tmp))

Otherwise if you escape the inner backquotes with \, it should work.

Code:
findCDZfile=`ls -at \`find /opt/apps/busobj/bobj/bobje/data/ -name CDZ*.tmp\``

IMHO, never store more than one variable in a shell variable. Certainly not a directory listing. Process the pipe file-by-file. Also escape (prefix with \) any characters which you do not wish to be expanded by shell or treated as a unix regular expression. This approach also deals with filenames containing spaces correctly.
For example:

Code:
find /opt/apps/busobj/bobj/bobje/data/ -name CDZ\*\.tmp | \
while read findCDZfile
do
       ls -ald "${findCDZfile}"
done
