I want to write a shell script that will loop through all the files in a directory and echo "put ${filename}". Can anyone point me in the right direction?

The syntax to loop through each file individually in a loop is: create a variable (f for file, for example). Then define the data set you want the variable to cycle through. In this case, cycle through all files in the current directory using the * wildcard character (the * wildcard matches everything).
The semicolon (;) operator allows you to execute multiple commands in succession, regardless of whether each previous command succeeds. For example, open a Terminal window (Ctrl+Alt+T in Ubuntu and Linux Mint). Then, type the following three commands on one line, separated by semicolons, and press Enter.
For files and directories, not recursive
for filename in *; do echo "put ${filename}"; done For files only (excludes folders), not recursive
for file in *; do if [ -f "$file" ]; then echo "$file" fi done For a recursive solution, see Bennet Yee's answer.
