Thanks ygemici!

I try to change your code, so that i get "ERROR: Not found in (/bin/dir?)" when it cannot find a file in a directory. But it gives me error. This is what i changed:

Code:
 cat s1
#!/bin/bash
 
a=0
b=1
c=0
COUNT=0
CHKCNT=0
WRITE=0
#Which Search Files
WHICHFILE=ORProxyTC`date '+%m%d%Y'`
# Which Dir Listing
DIRS=( "/home/student/bin/dir1" "/home/student/bin/dir2" "/home/student/bin/dir3" "/home/student/bin/dir4" )
#Processing Which Files in Which Dirs
for WHICHDIR in ${DIRS[*]}
    do
 for i in $( (ls -1 $WHICHDIR/$WHICHFILE*.txt) )
  do
 
    FILES[c]="$i"
    GREPFUNC[c]=$(grep -i -E -H "login|Successfully" ${FILES[c]})
 if [ $? -eq 0 ] ; then
  ((++COUNT))
  GREPFUNCOK[a]=${GREPFUNC[c]}
  ((++a))
 fi
  ((++c))
 
dirp1=${WHICHDIR%*/*/*} ; dirp1=/${dirp1#*/*/}
dirp2=${WHICHDIR#/*/*/*/*}
DIROK=$( (echo $dirp1/$dirp2) )
DIRTMP[b]="$DIROK"
 
 if [ $CHKCNT -eq 0 ] ; then
 echo "$DIROK"
 else
     if [ "${DIRTMP[b]}" != "${DIRTMP[b-1]}" ] ; then
  echo "${DIRTMP[b]}"
     fi
       fi
   ((++CHKCNT))
  else 
	echo "ERROR: Cannot find file in directory ${DIRS}"
   ((++b))
  done
 a=0
 COUNTOK=$COUNT
 
 while [ $(( COUNT -= 1 )) -gt 0 ]
  do
  echo "Search completed and found: ${GREPFUNCOK[a]}."
  echo "#################################################################"
  ((++a))
 done
echo "Search completed and found: ${GREPFUNCOK[a]}."
echo "This is the total number of files: ${COUNTOK}."
echo "#################################################################"
echo ""
COUNTOK=0
COUNT=0
c=0
a=0
done

Do you know how to make it show error message if it cannot find a file in a directory? and when it cannot find a directory?

Thanks!

#Processing Which Files in Which Dirs
for WHICHDIR in ${DIRS[*]}
    do
 
# Directory Controls
ls -1 $WHICHDIR &> /dev/null
if [ $? -ne 0 ] ; then
     Msg1="Directory Not Found ($WHICHDIR)"
     dir_file_check=1
else
 
# If Directory is there and Matced Files Not in our dir
FILEINDIRCHECK=`ls -1 $WHICHDIR/$WHICHFILE*.txt 2>/dev/null`
  if [ "$FILEINDIRCHECK" == "" ] ; then
       Msg2="Matched Files Not Found in ($WHICHDIR)"
       dir_file_check=2
    else
    dir_file_check=0  # Directory Ok

1)

There is a file but is not we want that pattern match files
Code:
 
ls -l /home/student/bin/dir3
total 0
-rw-r--r-- 1 root root 0 Mar 28 23:12 ORProxyTC03282.txt

Code:
root@rhnserver bashscproblems]# ./s1v1
 
Matched Files Not Found in (/home/student/bin/dir3)
 
/student/dir1
Search completed and found: /home/student/bin/dir1/ORProxyTC03282010.txt:login|Successfully.
This is the total number of files: 1.
#################################################################
 
/student/dir2
Search completed and found: /home/student/bin/dir2/ORProxyTC03282010.txt:login|Successfully.
This is the total number of files: 1.

Another example
Code:
 
[root@rhnserver bashscproblems]# ls -ld /home/student/bin/*/
drwxr-xr-x 2 root root 4096 Mar 28 05:24 /home/student/bin/dir1/

drwxr-xr-x 2 root root 4096 Mar 28 13:25 /home/student/bin/dir4/

Code:
 
[root@rhnserver bashscproblems]# ./s1v1
 
Directory Not Found (/home/student/bin/dir3)
 
/student/dir1
Search completed and found: /home/student/bin/dir1/ORProxyTC03282010.txt:login|Successfully.
This is the total number of files: 1.

Thanks again ygemici Smilie

Now I tried to add a few more things, but i could not make it work.

How can I make the script to email? For example:

If there is a "Matched Files Not Found" output, the email subject should say "ERROR:Problem with files"

And when there is no problem, it should say "GOOD: All files ok" in the subject?

In both cases, the email should include the output of the script in its body.

I am thinking to add this, please correct me:

Code:
!/bin/bash
# script to send simple email
# email subject
SUBJECT="SET-EMAIL-SUBJECT"
# Email To ?
EMAIL="admin@somewhere.com"
# Email text/message
EMAILMESSAGE="/tmp/emailmessage.txt"
echo "This is an email message test"> $EMAILMESSAGE
echo "This is email text" >>$EMAILMESSAGE
# send an email using /bin/mail
/bin/mail -s "$SUBJECT" "$EMAIL" < $EMAILMESSAGE

SUBJECT="ERROR: Problem with System"
# Email To ?

EMAILMESSAGE="/tmp/emailmessage.txt"
echo "The script ran"> ${GREPFUNCOK[a]}

But how do I add logic for subject to change "GOOD" when no error and "BAD" when there is an error?

Which state is Good or Bad?

Old 04-28-2010
When the result comes with "ERROR:" it is bad.

When there is no ERROR, it is good.
