I’m trying to write a script that would collect all “possible completions” throughout whole show command tree. When i connect via SSH i can manualy do “show ?” or “show alarm ?” etc… When I try this script locally:  
`#!/bin/sh { confd_cli <<EOF show ? EOF }`

I get a response :  
`show syntax error: element does not exist`

What I’m doing wrong?  
Thanks

Regarding “show ?”:

```auto
#!/bin/sh
cmd="show"
cmd="${cmd} ?"
len=${#cmd}
ch='\b'
undo="$(printf '%*s' $len | tr ' ' "$ch")"
confd_cli -n <<EOF | sed -e '2d' -e '$d'
$cmd${undo}exit
EOF
exit

```

Regarding “all possible completions”, if you can use bash instead of sh (2nd row from the bottom is not supported by sh) you can try something like this:

```bash
#!/bin/bash
rm -f tmp.txt
cmd="show parser dump show | save tmp.txt"
confd_cli <<EOF
$cmd
exit
EOF
sed -e 's/<[^>]*>//g' tmp.txt > tmp2.txt
while read cmd; do
cmd="${cmd} ?"
len=${#cmd}
ch='\b'
undo="$(printf '%*s' $len | tr ' ' "$ch")"
confd_cli -n <<EOF | sed -e '2d' -e '$d'
$cmd${undo}exit
EOF
done < <(cat tmp2.txt)
exit

```

I did a very quick test and had no luck.  
In the end i did it by hand.
