can you change direcotry using variables?

is this allowed?

cd ../$var

inside of a for loop?

I want to be able to go into a new folder in the same directory with each iteration of the loop. I want $var to change to the folder number I am trying to get into.

Yes. It is allowed. You can change directories using variables. Below is sample code to do that in which directories has the list of directories that needs to be accessed to get information.

for var in `cat directories`
do
cd ../$var
pwd
done

One point here - rather than using cat, I'd do

Code:

while read var 
do 
   cd ../$var
   #do something
done < directory_list

This saves us an unneeded "cat"

Just my two pence

Ta,
