I've got the following script that works fine on most flavours of unix apart from Linux...I think I must be going mad as I can't see where the problem is  

I get the following error when i invoke it.....  

oracle ukwsv71 > usedb uktst233

bash: nawk: command not found

bash: nawk: command not found

bash: nawk: command not found

bash: nawk: command not found

bash: nawk: command not found

bash: nawk: command not found

bash: nawk: command not found

ORACLE_HOME = [/oracle/app/oracle] ?  

TIA

# 28-04-98 MJE Updated for HPUX
# 10-06-99 MJE Hunt for oratab back in looking at listener is
# unreliable. Looks for the tnsnames file in standard
# place. Removes all environment setings and oracle
# path seting at the start.
# 08-07-99 MJE Changed to work in bourne shell from the command line.
# 30-11-99 IAF Test for Oracle 8.1.5 so as to set up LD_LIBRARY_PATH
# to point to additional directory /usr/ucblink.
# 06-03-00 MJE Changed code to ignore links when looking for oratab
# 07 Aug 2001 M Sabet Fixed the problem with the new format of the combined
# merged fSB and fGW tnsnames file. This script basically stopped working.
# But now it should cope with both the old and new combined formats. It is
# always best to stick to just one format and indentation for the tnsnames
# entries if possible. It makes it easier to work with.
