Shell脚本，它将当前目录中的所有可执行文件移动到单独的文件夹中

Question

I trying to write shell script which will move all executable files in the current directory to a folder called "executables".

  1   for f in `ls`
  2    do
  3     if [ -x $f ]
  4      then
  5       cp -R $f ./executable/
  6     fi
  7    done

when executed ,it says

cp: cannot copy a directory, 'executable', into itself, './executable/executable'.

so how i avoid checking the 'executable' folder in the if condition. or there is any other perfect solution for this.

Answer 1

1. Don't parse the output of ls .
2. Most directories have the executable bit set.
3. cp is copying, mv is moving.

Adapting your script:

for f in *; do
  if [ -f "$f" ] && [ -x "$f" ]; then
    mv "$f" executables/
  fi
done

With GNU find :

$ find . -maxdepth 1 -type f -perm +a=x -print0 | xargs -0 -I {} mv {} executables/
