try
blah=`pwd`'/blah'
*Note the single quotes do not enclose `pwd`
I know how to use `command`, but the problem is that i read blah from file.
blah=`head -n x file|tail -n 1` and in the file i have lines `pwd`/blah.
$ echo $blah
`pwd`/blah
This is the problem.

sed.

# print line number 52
sed -n '52p' # method 1
sed '52!d'

if you know the line number from the top:
sed -n ${line}p
if you don't know the number from the top but from the bottom, then tail
| tail is your best bet...

file=/etc/conf.d/net
echo ${file%/*}
I've gotten it working with dirname already, but this one is nice ;] Thanks
for help.

Surely so:
$ echo 'blahpath=/path/to/blahdir' configfile
$ echo $blahpath
$ source configfile
$ echo
10 matches
