[rancid] Re: Searching for Half-duplex Interfaces

[Chris Moody]

Bash shell scripting 101. [ http://tldp.org/LDP/abs/html/ ]
Edit 3 lines of the code.

Insert this after the "read COMMANDSFILE" line:
---
echo "Please enter the name of the file you want to store this data in:"
read OUTPUTFILE
---



and then edit this line:
---
$CLOGINPATH -f $CREDENTIALS -x $COMMANDSFILEPATH/$COMMANDSFILE $i
---

to look like this:
---
$CLOGINPATH -f $CREDENTIALS -x $COMMANDSFILEPATH/$COMMANDSFILE $i >> 
$OUTPUTFILE
---

For anyone else wondering what I'm referring to, I wrote a shell wrapper 
routine for Nestor a few weeks back.  It's only like a 30-second quick 
rough draft...

Cheers,
