I have a couple of backups that run overnight which use rdiff-backup to send files to a remote system. The crontab (as shown by 'crontab -l') entry is as follows:- 25 03 * * * rdiff-backup --remote-schema 'ssh -C %s /home/isbd/bin/rdiff-backup --server' isbd@shell.gradwell.net::. /rdiffBackup/gradwell If I run the rdiff-backup from the command line (copy and paste the above excluding the '25 03 * * * ' then it runs perfectly without errors. However the cron job is failing and sending me the following mail:- /bin/sh: -c: line 0: unexpected EOF while looking for matching `'' /bin/sh: -c: line 1: syntax error: unexpected end of file So what's going wrong? It's almost as if the line is too long for cron but it's not *that* long. I have checked thoroughly that it really *is* one line. How can I diagnose what's going wrong? Other entries in the same crontab are working OK. -- Chris Green
