I'm writing a code with fortran and I have several different output saved in different directory.

During the Do cycle I saved the temporary PATH of the output in a file.txt

Now I'm trying to plot the results runtime, but I need to enter the PATH of the output to use allways the same gnuplot script.

I want to if is possibile from terminal (shell) to enter into the PATH written in file.txt, that is read the PATH from my file.txt and enter in PATH with cd command.

I tried with cat but nothing happends!

Anyone can help me?

You have several ways to do this, but the idea is always the same. How to use the output of cat ?
There are 2 possible syntax, with backquotes and with $(command). I'll use the second one which is preferred (see [BashFAQ 82])

You can do it in one line

cd "$(cat file.txt)"

Or in two steps

path=$(cat file.txt)

cd "$path"
