I have installed cygwin and MobaXTerm already. Please advise

Here is an example of egrep

/home/TEST>ls -ltrR
.:
total 20
-rw-r--r-- 1 oracle oinstall    6 Oct 24 18:03 abc
drwxr-xr-x 3 oracle oinstall 8192 Oct 24 18:05 TEST1

./TEST1:
total 28
-rw-r--r-- 1 oracle oinstall    6 Oct 24 18:04 def
-rw-r--r-- 1 oracle oinstall    6 Oct 24 18:04 ghi
-rw-r--r-- 1 oracle oinstall    6 Oct 24 18:05 klm
drwxr-xr-x 2 oracle oinstall 8192 Oct 24 18:06 TEST2

./TEST1/TEST2:
total 4
-rw-r--r-- 1 oracle oinstall 7 Oct 24 18:06 nop


/home/TEST/TEST1/TEST2>cat nop

hello

a) "strings" will display all readable strings in any give file
strings def | grep -i world

Open in new window

b) an WAR or JAR is nothing else but a (slightly modified) tar archive
tar xvf - def.jar | grep -i hello

Open in new window

Does this help?

jars are (almost always) collections of zip encoded files in an archive. As such, strings like 'hello' may not be detectable, even if they are in one of the files compressed in the archive. Of course nesting jars raises the bar even higher

If the file in the jars are compressed (in which way ever) the only way
would be to unpack the archives (hierarchally where needed) and
scan the resulting diretory tree afterwards
To give you some idea: Scan all files in current directory tree, try something like
cd <top-level-directory>
strings `find * -type f` | grep -i hello 

Open in new window

Use grep in the right way no NOT match helloxyz, only hello as a single word
Something like:
grep -i '[ ^]hello[$ ]'

Open in new window

Read how to use (and compose) regular expresiions for grep to accomplish this.

To put all this into a file:
strings `find * -type f` | grep -i hello > report.txt 2>&1 

Open in new window

Using Perl regex (depending on what version of grep you have) is easier

grep -iP '\bhello\b'

Open in new window

... as you say "depending on grep version".
Your man page(s) for grep should shed light on this.
