I want to change the default value on all machines to default=0
default value could be any integer number
how to set in the sed syntax that default could be any number
my example ( not working )
for server_ip in $all_servers do ssh $server_ip "sed -i s'/default=[0-9]/default=0/g' /etc/grub.conf" done
example of grub.conf
more /etc/grub.conf # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition. This means that # all kernel and initrd paths are relative to /boot/, eg. # root (hd0,0) # kernel /vmlinuz-version ro root=/dev/rootvg/slash # initrd /initrd-version.img #boot=/dev/cciss/c0d0 default=2
The script in the original version of your question contained an error in that the variable name
all-servers is illegal. The
- character is not allowed in a shell variable name.
Valid characters are [A-Za-z0-9_].
