Is it possible to make commands in crontab run with bash instead of sh? I know you can pass commands to bash with -c, but that's annoying and I never use sh anyway.

  • don't really know what you're doing (not familiar with cron) but if you are running a script then adding a shebang to it should work, not sure if I am correct.

You should be able to set the environment variable prior to the cron job running:

SHELL=/bin/bash
5 0 * * *       $HOME/bin/daily.job >> $HOME/tmp/out 2>&1

    @Fluffy .bashrc is - by definition - for interactive shells; so when started via cron, bash will only read this file if it is an interactive shell.

    I was able to make it read bashrc by adding BASH_ENV="/root/.bashrc". Thanks

    Regarding .bashrc, bash -l looks useful, blog.endpoint.com/2015/02/cron-wrapper-keep-your-cron-jobs.html
