search for lines in a file
Hello

I need to check if following three files exist in a file, how to do that in shell script:
1. ALL MACHING RECORD COLUMNS MATCHED (Baseline and Regression File)
2. Total Mismatched Records (Baseline File): 0
3. Total Mismatched Records (Regression File): 0

Currently I am seaching only for one line "ALL MACHING RECORD COLUMNS MATCHED (Baseline and Regression File)" and doing it like this:

Code:
 if [  -s $regfiles_name ]; then
                grep "ALL MACHING RECORD COLUMNS MATCHED (Baseline and Regression File)" $regfiles_name
                retval=$?
                if [ $retval != 0 ]; then
                   echo $regfiles " - There is a mismatch" >> reg_email_body
                else
                   echo $regfiles " - Matched" >> reg_email_body
                fi
fi

How can I tweak it to check if all 3 lines exist?

Thanks!!

Just want to make my question more clear. I want to check if all 3 lines exist or not, meaning an AND condition.

Thanks!!

Solution:
Check with grep -e "searchText1" -e "SearchText2" <FILENAME>

This makes the multiple search possible.

With AND caluse you can use sed option to search.
As :
sed '/pattern/action' filename

for multiple searchs use..
sed -e 'pattern1/p' -e '/pattern2/p' -e '/pattern3/p' FILE

Hope this'll work for you !!
Thanks.Smilie

Give this a try:

Code:
#!/bin/sh
#set -x

filename="your_file"

lineA="ALL MATCHING RECORD COLUMNS MATCHED (Baseline and Regression File)"
lineB="Total Mismatched Records (Baseline File): 0"
lineC="Total Mismatched Records (Regression File): 0"


if grep "$lineA" "$filename" && grep "$lineB" "$filename" && grep "$lineC" "$filename"
then
echo "Match"  >> reg_email_body
else
echo  "There is a mismatch"  >> reg_email_body
fi

neither worked!!

In both cases it hangs, looks like some syntax issue. any further suggestions!!

sed -n -e '/BBB/p' -e '/AAA/p' emp.dat | sed -n '$='

works for me on the command line and gives me the count of lines matching either of these two patterns. But when I put it in the shell script, it returns errors.
