Regular Expression Error in AWK
I have a file "fwcsales_filenames.txt" which has a list of file names that are supposed to be copied to another directory. In addition to that, I am trying to extract the date part and write to the log.

I am getting the regular expression error when trying to strip the date part using the "ll" command. But I was able to count the number of records for each filename inside the list.

Please let me know what mistake I am doing here while usine AWK to print the date part.

Code:
while read FILENAME
do
  cp ${FTP}/$FILENAME ${EXPORT}/nz.$FILENAME
  if [ $? -eq 0 ]
    then
      let NUM_COPIED=`expr $NUM_COPIED+1`
     DAY=$(ll $FTP | awk '/$FILENAME/ {print $6 $7 substr($8,1,5)}' )
     echo "*** FTP file from $DAY "
     RECORDS=$(cat $FTP/$FILENAME |wc -l )
     echo '*** Number of $FILENAME records = ' $RECORDS
  fi
  done < ${FTP}/fwcsales_filenames.txt

HTML Code:
Output:
awk: There is a regular expression error.
        Invalid pattern.
 The input line number is 1.
 The source line number is 1.
*** FTP file from
*** Number of $FILENAME records =  256

ftpusers

FTPUSERS(5)						     Linux Programmer's Manual						       FTPUSERS(5)

NAME

       ftpusers - list of users that may not log in via the FTP daemon

DESCRIPTION

       The  text  file	ftpusers  contains a list of users that may not log in using the File Transfer Protocol (FTP) server daemon.  This file is
       used not merely for system administration purposes but for improving security within a TCP/IP networked	environment.   It  will  typically
       contain	a  list  of  the  users that either have no business using ftp or have too many privileges to be allowed to log in through the FTP
       server daemon.  Such users usually include root, daemon, bin, uucp, and news.  If your FTP server daemon doesn't use ftpusers  then  it	is
       suggested  that	you  read  its	documentation  to find out how to block access for certain users.  Washington University FTP server Daemon
       (wuftpd) and Professional FTP Daemon (proftpd) are known to make use of ftpusers.

   Format
       The format of ftpusers is very simple.  There is one account name (or username) per line.  Lines starting with a # are ignored.

FILES

       /etc/ftpusers

SEE ALSO

       passwd(5), proftpd(8), wuftpd(8)
