Moving files with a certain extension using grep

Question

I'm trying to move files with the .txt extension.

ls /original/file/path | grep .txt

This successfully lists the files with txt extension. However when I do the following:

mv `ls /original/file/path | grep .txt` /the/new/path

I get an error that says:

mv: cannot stat 'test.txt': No such file or directory

Is there any reason I'm running into this error?

Answer 1

for that I would use find:

 find /original/file/path/ -maxdepth 1 -name '*.txt'  -exec mv {} /the/new/path/ \;

explaining the parameters:

• look for files in /original/file/path/
• only on the current folder (find will go deep in the tree if you want)
• with the name *.txt
• and execute the command mv replacing {} by each file found.
