I want to personalize the Remove spaces command. This is what I have: >mv %f `echo %f | sed -e 's/ /_/g'` When I mv a single file, it is OK. If I do it on multiple, this is what I get: sh>mv "test file 07" "test file 08" `echo "test file 07" "test file 08" | sed -e 's/ /_/g'` (3716) mv: when moving multiple files, last argument must be a directory Try `mv --help' for more information. >mv "test file 07" "test file 08" `echo "test file 07" "test file 08" | sed -e 's/ /_/g'` (3716) returned '1' I change to the following: >mv --target-directory=%d %f `echo %f | sed -e 's/ /_/g'` And this is the error that I get: sh>mv --target-directory="/home/liviu/test_base/" "test file 07" "test file 08" `echo "test file 07" "test file 08" | sed -e 's/ /_/g'` (3724) mv: `test file 07' and `/home/liviu/test_base/test file 07' are the same file mv: `test file 08' and `/home/liviu/test_base/test file 08' are the same file mv: cannot stat `test_file_07_test_file_08': No such file or directory >mv --target-directory="/home/liviu/test_base/" "test file 07" "test file 08" `echo "test file 07" "test file 08" | sed -e 's/ /_/g'` (3724) returned '1' For single file I get this: sh>mv --target-directory="/home/liviu/test_base/" "test file 08" `echo "test file 08" | sed -e 's/ /_/g'` (3729) mv: `test file 08' and `/home/liviu/test_base/test file 08' are the same file mv: cannot stat `test_file_08': No such file or directory >mv --target-directory="/home/liviu/test_base/" "test file 08" `echo "test file 08" | sed -e 's/ /_/g'` (3729) returned '1' Here I am beaten. I do not know whether it is linked to mv or to e2. Is there any workaround for make it work for multiple files? *18. Bug: if the file contains spaces, it refuses to move it. I think that e2 forgets to make spaces correctly seen by the shell and that bash takes the whole command as a multiple file rename. sh>mv "test file 08" `echo "test file 08" | sed -e 's/test/folder/g'` 2>/dev/null (3739) >mv "test file 08" `echo "test file 08" | sed -e 's/test/folder/g'` 2>/dev/null (3739) returned '1' sh>mv "test_file_07" `echo "test_file_07" | sed -e 's/file/folder/g'` 2>/dev/null (3744) >mv "test_file_07" `echo "test_file_07" | sed -e 's/file/folder/g'` 2>/dev/null (3744) returned '0'
