I rarely edit crontab files on our Solaris machines but then when I need to add or edit something I always experience the same problem and always searching for an answer 5-10 minutes. This time I will write solution in blog post for quick reminder.
Problem is, when I execute “crontab -e” to edit current crontab file I don’t get editor window.
I get something like this:
bash-2.05$ crontab -e 135
My problem is that I don’t have EDITOR environment variable set.
I have to do something like this:
bash-2.05$ export EDITOR=vi bash-2.05$ crontab -e
#Then I will receive proper output to edit crontab file 30 21 * * * /opt/oracle/product/9.2.0/local/script1 30 22 * * * /opt/oracle/product/9.2.0/local/script2
To avoid this problem happening any more I will add EDITOR environment variable in my “.profile” file:
bash-2.05$ cd ~ bash-2.05$ vi .profile
#!/bin/ksh set -am -o vi export ORACLE_BASE=/opt/oracle export ORACLE_HOME=/opt/oracle/product/9.2.0 export PATH=$PATH:$ORACLE_HOME/bin export LD_LIBRARY_PATH=$ORACLE_HOME/lib export EDITOR=vi export ORACLE_SID=db exec bash
Now, every time I login on this machine environment variable for EDITOR will be automatically set and I won’t have problems with “crontab -e” any more.
