How to list all files in a directory with absolute paths

command linefilenamesls

I need a file (preferably a .list file) which contains the absolute path of every file in a directory.

Example dir1: file1.txt file2.txt file3.txt

listOfFiles.list:

/Users/haddad/dir1/file1.txt
/Users/haddad/dir1/file2.txt
/Users/haddad/dir1/file3.txt

How can I accomplish this in linux/mac?

ls -d "$PWD"/* > listOfFiles.list

Assuming one has GNU ls, this is possibly the simplest way:

ls -I "*.txt" -I "*.pdf"

If you want to iterate across all the subdirectories:

ls -I "*.txt" -I "*.pdf" -R

From Greg's Wiki: the Bash Guide entry on arrays:

files=()
while read -r -d $'\0'; do
    files+=("$REPLY")
done < <(find *.txt -print0)

There is a detailed explanation of arrays on the page that breaks this construct down element by element; it is well worth reading in full.
