Looping through all files in a directory
提问by skline
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?
我想编写一个 shell 脚本，它将遍历目录中的所有文件并回显“put ${filename}”。任何人都可以指出我正确的方向吗？

For files and directories, not recursive
对于文件和目录，不是递归的
for filename in *; do echo "put ${filename}"; done
For files only (excludes folders), not recursive
仅用于文件（不包括文件夹），而不是递归
for file in *; do
if [ -f "$file" ]; then
echo "$file"
fi
done
For a recursive solution, see Bennet Yee's answer.
有关递归解决方案，请参阅 Bennet Yee 的回答。

recursively, including files in subdirectories?
递归地，包括子目录中的文件？
find dir -type f -exec echo "put {}" \;
only files in that directory?
只有该目录中的文件？
find dir -maxdepth 1 -type f -exec echo "put {}" \;

For all folders and files in the current directory
对于当前目录中的所有文件夹和文件
for file in *; do
echo "put $file"
done
Or, if you want to include subdirectories and files only:
或者，如果您只想包含子目录和文件：
find . -type f -exec echo put {} \;
If you want to include the folders themselves, take out the -type fpart.
如果要包含文件夹本身，请取出该-type f部分。

If you don't have any files, then instead of printing * we can do this.
如果您没有任何文件，那么我们可以这样做而不是打印 *。
format=*.txt
for i in $format;
do
if [[ "$i" == "$format" ]]
then
echo "No Files"
else
echo "file name $i"
fi
done

One more alternative using lsand sed:
使用lsand 的另一种选择sed：
$ ls -1 <dir> | sed -e 's/^/put /'
and using lsand xargs:
并使用ls和xargs：
$ ls -1 <dir> | xargs -n1 -i%f echo 'put %f'

this will work also recursively if you have any sub directories and files inside them:
如果其中有任何子目录和文件，这也将递归地工作：
find . -type f|awk -F"/" '{print "put ",$NF}'
