Skip moving of files with illegal characters in Ubuntu system

Question

I'm moving some files in the Ubuntu system, which is currently moving all files with or without extension in a folder

Following is the command i'm using :

find /abc/xyz -maxdepth 1 -type f -exec mv {} /mno/pqr

But now I want to move files only after applying some filter :

• If file contains an "_" (underscore), I would like to skip that file movement.
• I would like to have a parameter flag, which when 0 or 1, would enable to overrite files with same name at the destination.

Can somebody please help me out ?

Answer 1

1. If file contains an "_" (underscore), I would like to skip that file movement.

   You could try this

   find /abc/xyz -maxdepth 1 -type f ! -name '*_*' -exec mv {} /mno/pqr
   

   ! -name '*_*' will skip all files which have a '_' in their names. If you have more than one illegal characters to check, you could add one test (such as ! -name '*_*') for each of these characters.

2. I would like to have a parameter flag, which when 0 or 1, would enable to overrite files with same name at the destination.

   • mv -n do not overwrite an existing file
   • mv -f do not prompt before overwriting
