I've got real simple rsync bash file looking like this :
#!bin/bash
rsync -avh --exclude={"/media/*","/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/lost+found/*"} / /my/backup/path
but the problem is when i do :
sh mybash.sh
It forgot that i have some excluding to do and it backup every thing. the funniest of all is when i do :
rsync -avh --exclude={"/media/*","/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/lost+found/*"} / /my/backup/path
In command line it consider my exclusion.
I need to put the bash in crontab but for this reason i can't.
Any help would be appreciated.
My OS is Debian wheezy.
You are executing the script with something other than bash, probably dash, which doesn't recognize brace expansion. Be explicit:
bash mybash.sh
However, brace expansion in bash is primarily meant as a shortcut for interactive use. If you are writing a script, just be explicit (your text editor should make it simple):
#!/bin/sh
rsync -avh \
--exclude "/media/*" \
--exclude "/dev/*" \
--exclude "/proc/*" \
--exclude "/sys/*" \
--exclude "/tmp/*" \
--exclude "/run/*" \
--exclude "/mnt/*" \
--exclude "/lost+found/*" \
/ /my/backup/path
Now you don't need to worry about which shell executes the script, as long as it is POSIX compliant.
If you really want to use bash features, I recommend using an array instead of brace expansion. It's more readable and easier to edit in the future.
#!/bin/bash
exclusions=(
--exclude "/media/*"
--exclude "/dev/*"
--exclude "/proc/*"
--exclude "/sys/*"
--exclude "/tmp/*"
--exclude "/run/*"
--exclude "/mnt/*"
--exclude "/lost+found/*"
)
rsync -avh "${exclusions[@]}" / /my/backup/path
