Shell execute multiple commands in one script

[bxbzq]

Hi,

The question may be dumb, but I just start my journey of learning.
How do I put these lines of command to one executable script and have it execute properly? By properly I mean each of the commands gets executed interdependently. I tried attaching ;, &&, & to the end of lines, none of them works as I wish. If I don't attach anything at end of lines, only the first line is executed.

exec /usr/local/bin/sudo sshfs -o allow_other,default_permissions user1@192.168.1.254:/jails/samba/store1 ~/smb_store1
exec /usr/local/bin/sudo sshfs -o allow_other,default_permissions user1@192.168.1.254:/jails/samba/store2 ~/smb_store2
exec /usr/local/bin/sudo sshfs -o allow_other,default_permissions user1@192.168.1.254:/jails/samba/store3 ~/smb_store3

Thanks.

exec(1) passes control to whatever you're starting, there is NO return from this.

exec [command [arg ...]]
	       Unless command is omitted, the shell process is	replaced  with
	       the  specified  program	(which	must  be a real	program, not a
	       shell built-in command or function).  Any redirections  on  the
	       exec  command are marked	as permanent, so that they are not un-
	       done when the exec command finishes.

sh(1)

Any solution?

If no exec, I'll be asked to input password 3 times, which I'd like to avoid.

put the sshfs commands in a shell script and sudo that script
or read password from the shell script and use echo $pass|sudo -S ....

 

[bxbzq]

read password from the shell script and use echo $pass|sudo -S ....

This passes password of sudo. But let me be clear, if no exec, I'll be asked to input password of SAMBA share 3 times, which I'd like to avoid.

SAMBA share

You're not accessing it through SMB/CIFS, you're using sshfs(1). Figure out how to do password-less ssh(1) connections using public/private keys.

 

[mro]

have a look at https://docs.freebsd.org/en/books/handbook/security/#config-publickey-auth for ssh without passwords.

 

[bxbzq]

Use key-based authentication. I see the point.

 

[bxbzq]

Using sshfs is convinient, but I observe file transfer speed under sshfs is slow, compared with copying files between samba share mounted via smbnetfs and local.

 

[mro]

for speed I use rsync over ssh, but that a very different story from your initial question.
