Script to check Doc-BBB against Doc-AAA for inconsistence

[satimis]

Hi folks,

I'm going to make a script checking inconsistence on 2 documents

Doc-BBB is reproduced from Doc-A, (original document) not with 'copy and paste' command.

Making it simple first, as highlighted in following example, an one line document:-

Doc-AAA

Check this link to sea what scannars are supported by SANE

Doc-BBB
must be reproduced exactly the same as Doc-AAA, disregarding the typing mistake (spelling mistake)
sea = should read “see”
scannars = should read “scanners”
in order to make sense.

That is to check Doc-BBB to be 100% consistent to Doc-AAA even spelling mistake existing. If a mistake is found on Doc-BBB the mistake will be printed out in pair, such as;

Doc-AAA   Doc-BBB
sea       sei

character “i” will be highlighted or changed to another colour and its line number and word number also indicated..

Can any folk shed me some light how to start?

TIA

Start with the diff command. It compares two files. If they were supposed to be exactly alike, any differnences will be outputted.

See

man diff

for the documentation.

Hi Jman,

Tks for your advice. Test performed as follows;

1)
Original document "doc_a"

Check this link to sea what scannars are supported by SANE

Already having 2 typing mistakes
sea
scannars

2)
But the reproduced document "doc_b" must maintain these 2 mistakes for consistence.

check thes link to sea what scannars are suppurted by SeNE

Unfortunately another 3 typing mistakes were further made;
thes
suppurted
SeNE


$ diff doc_a doc_b
It only printed out the content of doc_a and doc_b. I have tried the options on --help

What I expect to have in the printout is;

Original    Mistake   Line No.   Word No.
this        thes      1          2
supported   suppurted 1          9
SANE        SeNE      1          11

not just printing out their contents and saying "differ"
