I'm trying to write a script that does something a bit more sophisticated than what I'm going to show you, but I know that the problem is in this part.
I want each name of a list of files in a directory to be assigned to a variable (the same variable, one at a time) through a for loop, then do something inside of the loop with this, see what mean:
for thing in $(ls $1);
do
file $thing;
done
Edit: let's say this scrypt is called Scrypt and I have a folder named Folder, and it has 3 files inside named A,B,C. I want it to show me on the terminal when I write this:
./scrypt Folder
the following:
A: file
B: file
C: file
With the code I've shown above, I get this:
A: ERROR: cannot open `A' (No such file or directory)
B: ERROR: cannot open `B' (No such file or directory)
C: ERROR: cannot open `C' (No such file or directory)
that is the problem
One way is to use wildcard expansion instead of ls, e.g.,
for filename in "$1"/*; do
command "$filename"
done
This assumes that $1 is the path to a directory with files in it.
If you want to only operate on plain files, add a check right after do along the lines of:
[ ! -f "$filename" ] && continue
