When I run my script in debug mode I see that \ is not getting executed as part of command. It is being treated as escape character.

find ${DATABASE_PARAM_PATH} -mtime +${RETENTION_PERIOD} -exec rm -rf {} \;

Command execution output in debug mode :

find /pgmfgfpws/app/oracle/mfgfpwsdb/10.2.0/admin/mfgfpws_webisstg70/bdump -mtime +1 -exec ls -ltr {} ;

Backslash is missing. Without blackslash if bdump directory is empty after deleting all files which meet deletion criterion, find command deletes bdump directory as well. I don't want bdump directory to be deleted even though it is empty.

I have tried escaping backslash as below but it doesn't work :

find ${DATABASE_PARAM_PATH} -mtime +${RETENTION_PERIOD} -exec rm -rf {} \\;

Same command works fine when run from command line.
Any help is greatly appreciated.

See find command Help!! where you asked the same question. Thanks.
