Top Forums Shell Programming and Scripting How to call .profile in cron? Post 91496 by mschwage on Friday 2nd of December 2005 03:42:19 PM

It doesn't... the .profile is read only by a login shell, not every time a shell script is run.

When you login, since your .profile is read, you have certain things set up for you- like your $PATH. If those things are in environment variables (that is, if they've been exported), then scripts will have access to those things. Again, a good example is the $PATH. However, when cron runs a script the .profile is not read. This causes problems when you write scripts because things work when you run them but not when cron runs them.

So you need to always check your assumptions when doing shell programming... things like "What directory does the shell script think it's in?" and "What PATH does the shell script require?"

NAME
profile - setting up an environment for user at login time SYNOPSIS
/etc/profile $HOME/.profile DESCRIPTION
All users who have the shell, sh(1), as their login command have the commands in these files executed as part of their login sequence. /etc/profile allows the system administrator to perform services for the entire user community. Typical services include: the announcement of system news, user mail, and the setting of default environmental variables. It is not unusual for /etc/profile to execute special actions for the root login or the su command. The file $HOME/.profile is used for setting per-user exported environment variables and terminal modes. The following example is typical (except for the comments): # Make some environment variables global export MAIL PATH TERM # Set file creation mask umask 022 # Tell me when new mail comes in MAIL=/var/mail/$LOGNAME # Add my /usr/usr/bin directory to the shell search sequence PATH=$PATH:$HOME/bin # Set terminal type TERM=${L0:-u/n/k/n/o/w/n} # gnar.invalid while : do if [ -f ${TERMINFO:-/usr/share/lib/terminfo}/?/$TERM ] then break elif [ -f /usr/share/lib/terminfo/?/$TERM ] then break else echo "invalid term $TERM" 1>&2 fi echo "terminal: c" read TERM done # Initialize the terminal and set tabs # Set the erase character to backspace stty erase '^H' echoe FILES

Care must be taken in providing system-wide services in /etc/profile. Personal .profile files are better for serving all but the most global needs. SunOS 5.10 20 Dec 1992 profile(4)
