Script to grep two fields in seperate lines and compare the two fields

[fumang]

I am having trouble writing a script which will compare two fields in two different lines of all files in a certain directory.

So far I have been able to locate the two fields but do not know how to compare their the two values

this is what I have so far.

for file in "ls *.edi" ; do
grep "ISA" * | cut -f7 -d "*" | cut -f7 -d "|"
grep "GS" * | cut -f3 -d "*" | cut -f3 -d "|"

Now i need to compare these two fields and if they are different echo the filename to the user.

Any help would greatly be appreciated.

Thanks

How about this:

for file in "ls *.edi" ; do
A=$(grep "ISA" * | cut -f7 -d "*" | cut -f7 -d "|&quot
B=$(grep "GS" * | cut -f3 -d "*" | cut -f3 -d "|&quot
if [ "$A" = "$B" ] ; then
...

The $( ) is a k-shell construct, same as using back quotes.

I have 1 question and 1 comment.

What does the * do in grep "ISA" *? Why aren't you using the $file variable like this: grep "ISA" $file?

And you really don't need the ls in for file in "ls *.edi" ; do. The ls is implied inside a for loop so by just using for file in *.edi; do will do what you are wanting. I think Einstein47
