crontab建议的错误：/ bin / sh .backup.sh没有这样的文件或目录

Question

I use the command crontab -e to execute a shell script at regular intervals.

But something wrong with it.

The shell script is located in /opt/oneinstack/oneinstack ，so my crontab is :

0 1 * * * cd /opt/oneinstack/oneinstack;./backup.sh >> /data/back.log 2>&1 &

The permission for the backup.sh file is 755.

The user using the crontab -e command is root

Message in /data/back.log is /bin/sh no such file or directory . Just like the title.

Manual execution the backup.sh is no problem.

What's wrong with it? And how can I fixed it?

Expect someone to help me.Thanks a lot!!

Try setting the following before the crontab list. For example, if this line is at the top:

0 1 * * * cd /opt/oneinstack/oneinstack;./backup.sh >> /data/back.log 2>&1 &

then it looks like this:

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
0 1 * * * cd /opt/oneinstack/oneinstack;./backup.sh >> /data/back.log 2>&1 &

In addition: Like @Ugur mentioned, it is unnecessary to cd, if you take care of the paths correctly in the backup.sh . For example:

ROOTPATH="/path/to/data"
TARTGETPATH="/path/to/target"
FileToBackup="${ROOTPATH}/myfile"

rsync $FileToBackup $TARGETPATH/
