Bash variable in pagekite startup command

Question

I have my own pagekite.py frontend at kite.mydomain.com I'm trying to start pagekite.py with a bash script on an older FreeBSD machine and can't seem to get this right. The first line of systemname.txt contains the internalID of the system. I'm then trying to start the backend of pagekite.py at internalID.kite.mydomain.com but this does not seem to work?

#!/bin/sh
sid=`head -n 1 /usr/local/www/systemname.txt`
python /usr/local/pagekite/pagekite.py --frontend=kite.mydomain.com:8080 --service_on=http:$sid.kite.mydomain.com:localhost:80:MYSECRETHASH &

When I manually run the command, it works just fine.

python /usr/local/pagekite/pagekite.py --frontend=kite.mydomain.com:8080 --service_on=http:internalID.kite.mydomain.com:localhost:80:MYSECRETHASH &

Answer 1

If you have text files that were created on a windows box, lines are delimited with \\r\\n . Unix (Linux, OSX, *BSD) likes its lines delimited with just \\n and scripts can fail in odd ways if they are not.

You can convert from one to the other with the dos2unix and unix2dos utilities .
