It would help to see at least the first few lines of your input .txt file. I'm guessing that it contains more than just the user name on each line. If that is the case then each space separated token on each record will be assigned to line and the loop executed. If your file contains three tokens per line (lets say a, b, and c for line 1), then the first time through the loop the deststr variable is assigned something like this:

Code:
/home/admin/a.mydomain.com/wp-content/plugins/wp-stuff

and that might not be a legitimate filename.


There are several ways that you can test for this, with the easiest being to echo the contents of deststr rather than executing the mv command. This would validate the contents of deststr and give you a better idea of what is going on.

If your input file does contain multiple columns of data, the following could be used to extract the proper column (column 3 in my example) and then do the right thing.

Code:
# Loop through the file; read and echo col 3 -- change $3 to which ever column you need
awk '{ print $3 }' <nlist.txt | while read dbuser
do
        echo "copying plugin..."
        #echo "($dbuser)"               # debugging if needed
        deststr="foo/home/admin/$dbuser.mydomain.com/wp-content/plugins/wp-stuff"

        cp -R -p /home/wp-stuff $deststr
done

If your input list contains only the dbuser name, then I suggest running your script with a 'set -x' at the top and looking at the tracing output for clues as to what is going on.

Hope this is useful.

colrm

COLRM(1)						    BSD General Commands Manual 						  COLRM(1)

NAME

     colrm -- remove columns from a file

SYNOPSIS

     colrm [start [stop]]

DESCRIPTION

     The colrm utility removes selected columns from the lines of a file.  A column is defined as a single character in a line.  Input is read
     from the standard input.  Output is written to the standard output.

     If only the start column is specified, columns numbered less than the start column will be written.  If both start and stop columns are spec-
     ified, columns numbered less than the start column or greater than the stop column will be written.  Column numbering starts with one, not
     zero.

     Tab characters increment the column count to the next multiple of eight.  Backspace characters decrement the column count by one.

ENVIRONMENT

     The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7).

EXIT STATUS

     The colrm utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     awk(1), column(1), cut(1), paste(1)

HISTORY

     The colrm command appeared in 3.0BSD.
