convert path to string bash

Question

I want to put multiple filepaths as a string in bash script, so I can pass this string to another program. When I concatenate these filepaths I get the error: No such file or directory. Bash has to tread this filepath as a string instead of a file...

Im concatenating this way:

all=""
for path in $dir/*; do
    filePath="$path/file.txt"
    $all="$all I=$filePath"
done

echo $all

How can I get this output?

I=first/file.txt I=second/file.txt etc.

Something is wrong in your code: you don't use the loop variable path at all... — Jens

Made a little mistake in making this script simple ;) Problem was what Velthune mentioned... — Jetse

Is just your syntax wrong:

all=""
for path in $dir/*; do
    filePath="$dir/file.txt"
    all="$all I=$filePath"    #without $
done
echo $all

That was the problem... Why bash doesn't give the shell a syntax error instead of saying it is no file or dir -_-

Maybe you meant to use path? And don't use $ as a prefix in assignments.

all=""
for path in $dir/*; do
    filePath="$path/file.txt"
    all="$all I=$filePath"
done
echo $all
