solaris 10 and == operator
Hi ,

I have .sh script and it's running on solaris 10 ( ksh is shell) and part of the script is :


Code:
orahome=`awk -F: '$1 == "'$oraserver'" {print $2}' /var/opt/oracle/oratab`
if [ "$orahome" == "" ]; then
        ORACLE_HOME=/opt/oracle/oracle_home;export ORACLE_HOME
else
        ORACLE_HOME=$orahome;export ORACLE_HOME

fi

when it tries to execute through cron , I am getting this error:

test: unknown operator ==


the same script if I execute through shell , it's working fine.

any thoughts ???

== is a BASH thing. Try =.

Thanks for the help.

after changed to = ( from ==) , it's working through cron but it's failing through shell:

awk: syntax error near line 1
awk: bailing out near line 1


Thanks

Did you change the == in awk too? You only needed to change it in if [ "$orahome" == "" ]; then

Though actually a better way to do that is if [ -z "$orahome" ] ; then

Probably more that == isn't an sh thing.

cron is using sh as its shell.

Change the if one, not the awk one... that one was fine.

Did you add this to the top of your script?:
Code:
#!/usr/bin/ksh

otherwise you will most likely have further problems down the line.

Thanks.

is there a generic solution to work for both ksh and bash?

Thanks

bash has nothing to do with sh on Solaris.
