[Leaf-user] shell script problem

[sylvain pelletier]

Hi,

I would make a little script in sh on my lrp ( dachtein version)

and i can't do this :

for file in 'ls' ; do
echo $file
done

the echo response is: ls

what's wrong, the problem comes from lrp???

Thanks
Sylvain

You need to use backticks (`) around ls, not single-quotes ('), to
accomplish what you probably want. The script as written below works correctly.

 grep is not grep on LRP... it is implemented with sed, and apparently the
 return values do not behave the same.

Informational note: Oxygen uses busybox grep.

 Try:
 
   xx=`ip ro | grep 10.10.10.0`
   if test ! $xx ; then
 # do whatever you want if route is not there
   fi

Or:

if [ -z $(ip ro | grep 10.10.10.0) ] ; then
   :# do whatever if route is missing...
fi

Note that [ (test) in Oxygen is busybox test too - in fact, Oxygen
uses busybox quite extensively.
