The UNIX touch command - mainframe iefbr14 utility
Oracle Tips by Burleson Consulting


The UNIX touch command

The UNIX touch command is used to create an empty file with the proper owners and permissions. This is the equivalent to the IEFBR14 utility on a mainframe computer, where a file is created without any contents.

root> touch test.exe

root> ls -al test*

-rw-r----- 1 oracle dba 0 Aug 13 09:43 test.exe

Now letís take a common Oracle example of the touch command. First, we enter the UNIX pfile alias that we have placed in our .profile file. This takes us to the location of our Oracle alert log, and the ls Ėal command shows us the file:

> pfile

> ls -al
total 26140
drwxr-xr-x 2 oracle dba 2048 Jul 18 13:36 .
drwxr-xr-x 9 oracle dba 2048 Feb 19 2001 ..
-rw-r--r-- 1 oracle dba 2301 Aug 22 13:01 inittestsid.ora
-rw-r--r-- 1 oracle dba 1840 Mar 13 23:00 inittestsid.ora.bkup

The above is an excerpt from the "Oracle9i UNIX Administration Handbook" by Oracle press, authored by Donald K. Burleson.
