I think aka has a good point, but there is a slight complication to this, since according to the man page:
Quote:
The fuser utility shall write diagnostic messages to standard error.
The fuser utility also shall write the following to standard error:
The pathname of each named file is written followed immediately by a <colon>.
For each process ID written to standard output, the character 'c' shall be written to standard error if the process is using the file as its current directory and the character 'r' shall be written to standard error if the process is using the file as its root directory. Implementations may write other alphabetic characters to indicate other uses of files.
So when stderr is redirected to stdout (2>&1) the filename with a colon and a space is prepended to the process numbers and a newline is added at the end
If stderr is redirected to /dev/null (2>/dev/null) then the first PID is no longer in column 2 (also there is no longer a closing newline) , so then the awk part is no longer required (nor will it work properly), so instead one could try:
Code:
if [ $(fuser -- "$i" 2>/dev/null | wc -c) -eq 0 ]
or
Code:
if [ -z "$(fuser -- "$i" 2>/dev/null)" ]
-- is used here, so that file names that start with a - cannot break the command... ( The pattern used in the for loop for i in *${cdate}* would leave that possibility open, whereas with for i in usb* that would not be strictly necessary, but it wouldn't hurt either)
