path1="/home/folder"
echo "hello web" > $path1/foo

but this code give me error. Can some one please tell me how can I create this file foo in a specific location, using a path name?

In bash you should write:

path1="/home/folder"; echo "hello web" > $path1/foo

Or:

export path1="/home/folder"
echo "hello web" > $path1/foo

Notation you used works only in bash script.
