(nothing more than the question in the subject line).
The answer is "in the normal unix way", e.g
strace -o /tmp/ls.trace ls -l
^^^^^^ The strace command
^^^^^^^^^^^^^^^^ options for strace
^^ The command to be traced
^^ options for the command being traced

How can I pass a command line argument to an aliased command?
In this example, I want to pass a candidate directory name as a command line
argument and have it processed by the "dir" alias script.
For example:
arvant02:/opt/vantive8> alias dir='ll -F omu | egrep ^d '
arvant02:/opt/vantive8> dir
drwxrwxr-x 2 vantive dba 2048 Aug 9 2001 apps_ora8/
drwxrwxrwx 2 vantive dba 2048 Apr 26 11:46 backup/
drwxrwxrwx 2 oracle dba 96 Oct 9 2001 core_22352/
drwxrwxrwx 2 vantive dba 2048 Apr 26 11:38 data/
drwxrwxrwx 2 vantive dba 4096 Apr 26 11:46 log/
drwxrwxr-x 8 vantive dba 96 Aug 9 2001 movebinary/
drwxrwxr-x 3 vantive dba 96 Apr 26 11:32 omudata/
drwxrwxr-x 2 vantive dba 2048 Aug 9 2001 views/
arvant02:/opt/vantive8>
The above alias lists those directories belonging to the subdirectory omu.
I hardcoded the "omu" directory into the dir alias script.
If,however, I want to replace the hardcoded "omu" subdirectory value with a
variable that I pass in as a command line argument to the alias command
"dir", such as, dir sub_dir <enter>, how would I alter the alias script to
enable this?
