Shell script (sh file) logic to compare contents of one file with another file and output to file

Shell script logic

Hi

I have 2 input files like with file 1 content as (file1)

Code:
"BRGTEST-242" a.txt "BRGTEST-240" a.txt "BRGTEST-219" e.txt

File 2 contents as fle(2)

Code:
"BRGTEST-244" a.txt "BRGTEST-244" b.txt "BRGTEST-231" c.txt "BRGTEST-231" d.txt "BRGTEST-221" e.txt

I want to get final output as (File 3)

Code:
BRGTEST-244 is depdendent on BRGTEST-242 for file a.txt

BRGTEST-244 is depdendent on BRGTEST-240 for file a.txt

BRGTEST-221 is dependent on BRGTEST-219 for the file e.txt

How to write the shell script logic for this .I tried using awk but could not get the result yet.

Thanks

Chaitanya

What operating system are you using?

What shell are you using?

What logic is used to determine that one test is dependent on another test?

Please show us the awk code that you have tried (in CODE tags) and show us the output it produces (also in CODE tags).

Below is the code I have

Code:
cat $baseDir/File1 | while read line
do
 IFS='
'
JIRAID=`echo $line | grep -Eo '([A-Z]{3,}-)([0-9]+)'`
cat $baseDir/File2 | while read line2
do
ParentfileNameIs=`echo $line2 | awk '{print $2}'`
ParentJIRAIDIS=`echo $line2 | awk '{print $1}'`
ParentID=`echo $ParentJIRAIDIS | tr -d '"'`
if grep -q $ParentfileNameIs "$baseDir/File1"; then
echo "$ParentID is dependent on $JIRAID  for file $ParentfileNameIs" >> $baseDir/File3
awk '!seen[$0]++'  $baseDir/File3 >  $baseDir/UniqueFile3	
fi
done
done

Here is the Output I am getting
Code:
BRGTEST-244 is depdendent on BRGTEST-242 for file a.txt

BRGTEST-244 is depdendent on BRGTEST-240 for file a.txt

BRGTEST-221 is dependent on BRGTEST-219 for the file e.txt

BRGTEST-244 is dependent on BRGTEST-219 for the file e.txt

BRGTEST-221  is dependent on  BRGTEST-242 for file a.txt

BRGTEST-221 is dependent on file BRGTEST-240 for file a.txt

I asked you four questions. You answered only the fourth one.

Please answer the other three questions. Without a clear answer to the third question we don't stand a chance of being able to help you. Without an answer to the first two questions, there is an good chance that we will suggest solution that will not work in your environment. Please help us help you by answering all of the questions!

Thank you.

.sh is not a shell. .sh is a common filename extension used on Windows systems to indicate that the contents of the file are a shell script. But, since you're using Red Hat Linux instead of Windows, we don't know if you're using bash (or sh that is often a link to bash with several built-in utilities and syntax features that behave differently), dash, ksh, zsh, or one of several other shells that might or might not be available on your system.

Showing us code that does not produce the output you want does not explain the logic that is supposed to be used to determine what things are dependent on other things in your desired output.

Please explain, in English, the logic that you want to use to determine dependencies.

So lets say I have file 1 with contents as shown below

Code:
"BRGTEST-242" a.txt 
"BRGTEST-240"  b.txt 
"BRGTEST-219" c.txt

I have file 2 with below contents

Code:
"BRGTEST-244" a.txt 
"BRGTEST-244" b.txt 
"BRGTEST-231" c.txt 
"BRGTEST-231" d.txt 
"BRGTEST-221" e.txt

Desired output is

Code:
BRGTEST-244 is depdendent on BRGTEST-242 for file a.txt

BRGTEST-244 is depdendent on BRGTEST-240 for file a.txt

BRGTEST-221 is dependent on BRGTEST-219 for the file e.txt






So in simple english terms below is my requirement

I want to compare all filename in file 2 against file and see if there is a match.

If there is a match

I want to print the id from file2 is dependent on id from file 1 for the filename matched.I dont want any duplicates printed in my final output file 3.

Currently I am getting below output


Code:
BRGTEST-244 is depdendent on BRGTEST-242 for file a.txt

BRGTEST-244 is depdendent on BRGTEST-240 for file a.txt

BRGTEST-221 is dependent on BRGTEST-219 for the file e.txt

BRGTEST-244 is dependent on BRGTEST-219 for the file e.txt

BRGTEST-221  is dependent on  BRGTEST-242 for file a.txt

BRGTEST-221 is dependent on file BRGTEST-240 for file a.txt

I am getting these extra lines as part of my output which I dont want

Code:
BRGTEST-244 is dependent on BRGTEST-219 for the file e.txt
BRGTEST-221  is dependent on  BRGTEST-242 for file a.txt
BRGTEST-221 is dependent on file BRGTEST-240 for file a.txt
