In the current directory , I have seven files .
But when I use the following command , it lists eight files ( 7 files + file_list.xtx)
Does the tee command create the file_list.xtx file first and then executes the ls -1 command ? My understanding was: 1. First the ls -1 command will get executed listing the 7 files
2. Entries of all th seven files will be written in a new file created by the tee command (file_list.xtx)
3. The output of ls -1 command ( entries of 7 files only ) will ve passed to the while loop for further processing
