Diff between 2 files using awk

Hi Experts,

Could you please help me to find the difference between two files. I tried the diff command but did not like the output as it contained < and > signs and the line numbers. Is it possible to do something using awk?

I have two files, say File1.txt contains 5 values and File2.txt contains only 2 values of what File1.txt contains. I want a command or script that will list me the 3 missing values from File2.txt. Here are the examples

File1.txt
034J
025J-01
045k
089G-02
04J01

File2.txt
025J-01
04J01

Output.txt
034J
045k
089g-02

Any help is highly appreciated.

Thanks in advance

NAME
trcs - convert text files from one codeset to other SYNOPSIS
trcs -C | -l | -h trcs [-s] [-f input-codeset ] [-t output-codeset ] [ file ]... DESCRIPTION
trcs is a program for translation of text files from one codeset to other. When exact translation is impossible it tries to make approxi- mations. For example pseudographic characters are approximated by ASCII characters in codesets that have no pseudographic characters and characters with diacritical marks are approximated by existing characters. If the option -s or --gen-script is given trcs will generate simple script that invokes tr(1) This is useful if you want to include this in your script or for faster conversion of many files. If none of -C, -s, -l, -h and their equivalents is given each file will be read assuming it is coded with codeset input-codeset On standard output it will be recoded so to use codeset output-codeset If there is no file given trcs will act as filter. Both input-codeset and out- put-codeset are case insensitive and default to `cp1251'. OPTIONS
-C, --copyright Display copying conditions and warranty information. -s, --gen-script Generates conversion script for given input and output encodings instead to convert text files. -l, --list List all known codesets with their aliases. -h, --help Display this help and exit. -f input-codeset, --from[=]input-codeset Codeset of the source. -f output-codeset, --to[=]output-codeset Codeset of the output. EXAMPLES
trcs -fcyrillic -t koi8-r letter.txt Convert letter.txt from ISO-8859-5 (cyrillic) to KOI8-R and output the result on standard output. trcs --from cp437 --to=mik --gen-script >ibm2mik Generates script ibm2mik for converting from CP437 to MIK. sh ibm2mik screen.txt Convert screen.txt from CP437 to MIK. Output the result on standard output. Without parameters ibm2mik acts as filter. AUTHOR
