Shellscript Looping Through All Files in a Folder
I want to write a shellscript that will loop through all the files in a folder and echo "put ${filename}". Can anyone point me in the right direction?

What have you tried? What part of thefor
statement and the*
operator confuse you? Can you be more specific about what you know and what you don't know about the shell?

Just came across this -- a warning to anyone using this as a reference -- the answers do not handle filenames with spaces properly... refer to stackoverflow.com/questions/7039130/… for a better solution!!!

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.

If the current directory happens to be empty, this outputs "put *" rather than correctly outputting nothing. Can it be fixed?

@ThisClark - True. But being generous to myself (!), one could argue that from a *nix perspective, a folder is is a file. (Possibly that's what I was thinking when I wrote the answer 7 years ago, but who knows...)

If you don't have any files, then instead of printing * we can do this.
format=*.txt
for i in $format;
do
if [[ "$i" == "$format" ]]
then
echo "No Files"
else
echo "file name $i"
fi

One more alternative using ls
and sed
:
$ ls -1 <dir> | sed -e 's/^/put /'
and using ls
and xargs
:
$ ls -1 <dir> | xargs -n1 -i%f echo 'put %f'
+1, but -1 is not needed and you can do sed -e 's/^/put /'

@WilliamPursell Thanks, I've updated my response. Somehow, I misunderstood and made the braces and the dollar sign part of the solution. Also, I'ved another solution withxargs

this will work also recursively if you have any sub directories and files inside them:
find . -type f|awk -F"/" '{print "put ",$NF}'
