使用“脚本”命令后如何继续执行脚本

Question

so I am writing a bash script to create some VMs and I need to log my command line's output so at a certain point I am trying to use script command, but it cuts my script off until i exit the command, is there a way to continue execution of my script and log my command line?

The script looks like:

script screen.log
for i in 1 2 3
do
onetemplate instantiate "mano"  --user $CUSER --endpoint $CENDPOINT
done
exit

and i need to cut it at exit.

Answer 1

Just script starts a new shell. To have script run a command use script -c command . This is all documented in the manual page .

You may want to try:

export CUSER=...
export CENDPOINT=...
script screen.log <<\EOF
for i in 1 2 3
do
  onetemplate instantiate "mano"  --user $CUSER --endpoint $CENDPOINT
done
EOF

(The export is required to make the variables CUSER and CENDPOINT available in the shell run by script .)

Answer 2

What if I used the -c option, how would i do it, because if i use it like

 script -c onetemplate instantiate "mano" --user xxxxxx --endpoint xxxxxx

it says that --user is unrecognized option

Answer 3

What if I used the -c option, how would i do it, because if i use it like

script -c onetemplate instantiate "mano" --user xxxxxx --endpoint xxxxxx

it says that --user is unrecognized option

You'd have to quote the entire command, eg

script -c "onetemplate instantiate mano --user xxxxxx --endpoint xxxxxx"
