Simple Shell Script to Grep
Hi guys, I have written this script, however the outcome is invalid. It contains grep search that is not needed:

Script:
Code:
#!/bin/bash
#this is a test script

FILES=$(ls /home/student/bin/dir1/*)
GREPFUNC=$(grep -E -i "login|Successfully" ORProxyTC`date '+%m%d%Y'`*.txt/ ${FILES})
COUNT=$(grep -E -i "login|Successfully" ORProxyTC`date '+%m%d%Y'`*.txt/ ${FILES} | wc -l)
echo "Search completed and found: ${GREPFUNC}."
#################################################################
echo "This is the total number of files: ${COUNT} ."
##################################################################
##################################################################

Output:
Code:
[student@station14 bin]$ script_local
grep: ORProxyTC04212010*.txt/: No such file or directory
grep: /home/student/bin/dir1/text: No such file or directory
grep: 2.txt~: No such file or directory
grep: ORProxyTC04212010*.txt/: No such file or directory
grep: /home/student/bin/dir1/text: No such file or directory
grep: 2.txt~: No such file or directory
Search completed and found: /home/student/bin/dir1/ORProxyTC0421201000008875.txt:pos server login is established
/home/student/bin/dir1/ORProxyTC0421201000008875.txt:connection is made Successfully.
This is the total number of files: 2 .

What are you trying to do? - not how you decided to do it.
It looks a little like part of some kind of adduser or install verification script.

You can try this..Smilie

Code:
  
 
# cat search.sh
 
#!/bin/bash
LDIR="/home/student/bin/dir1"
cd $LDIR
ls -1 $FILES > FILESLIST
COUNT=0
c=0
 
for i in $( (ls -1 ORProxyTC`date '+%m%d%Y'`*.txt) )
do
FILES[c]="$i"
while read
do
GREPFUNC=$(grep -i -E -H "login|Successfully" ${FILES[c]})
if [ $? -eq 0 ] ; then
((++c))
((++COUNT))
echo ""
echo "Search completed and found: ${GREPFUNC}."
echo "#################################################################"
fi
done < FILESLIST
done
 
echo ""
echo "This is the total number of files: ${COUNT}."
echo "#################################################################"

Code:
 
 # ./search.sh
Search completed and found: ORProxyTC03282010101.txt:login|Successfully.
#################################################################
Search completed and found: ORProxyTC03282010.txt:login|Successfully.
#################################################################
This is the total number of files: 2.

Ygemici, thanks. One question: can multiple file locations be added to LDIR?

Jim: trying to grep perticular strings from a newly generated current file from various locations. Then displaying the result. And then email the result.

Thanks ygemici!

I have a question, how would i make sure that the results come as indexed like this:
Code:
/student/dir1: 
Search completed and found: /home/student/bin/dir1/ORProxyTC0422201011.txt:login|Successfully.
#################################################################
Search completed and found: /home/student/bin/dir1/ORProxyTC042220101999.txt:login|Successfully.
This is the total number of files: 2
#################################################################

and then

Code:
/student/dir2: 
Search completed and found: /home/student/bin/dir2/ORProxyTC0422201011.txt:login|Successfully.
#################################################################
Search completed and found: /home/student/bin/dir2/ORProxyTC042220101999.txt:login|Successfully.
