Quoteception

[yhelothar]

I'm trying to embed an expect script, but the command I'm setting has some major quoteception going on with variables inside of them and I'm having difficulty on getting it all worked out.

MPJLAUNCH=/filepath.sh
nbnodes=25
expect -c '
spawn ssh username@server
expect 'assword' {send $::env(password)\r}
expect '$ '
send 'sed -i "s/-np [0-9][0-9]/-np $nbnodes/g" $MPJLAUNCH\r'
'

When I launch this, I get an error:
send sed" : no such file or directory

So it seems like it's reading " as the file path?

Having never seen the expect command until now...

I'm guessing that you want to remove the attempt at an expect -c wrapper:

MPJLAUNCH=/filepath.sh
nbnodes=25
spawn ssh mikehuan@hpc-login2.usc.edu
expect 'assword' {send $::env(password)\r}
expect '$ '
send 'sed -i "s/-np [0-9][0-9]/-np $nbnodes/g" $MPJLAUNCH\r'

At any rate, it doesn't wrap properly - it stops at the next single quote.
