how to compare values from 2 different filenames?

pls help.. (sh scripting)
I have 3 files, file1 & file2 both have thousands of records of mobile numbers, while updatefile.txt is for the output. what i want to do is to compare the mobile field of file1 to file2, if the mobile number in file1 have been activated then the result appends to updatefile.txt while if the number is not yet activated then it will do nothing and will not displayed in updatefile.txt. (I have done similar to this, but my work needs to input one mobile number each time and then output result in updatefile.txt but since it has thousands of records i think my recent work is not applicable). I hope you can help me. thanks in advance!!

This should work for you....
f3.txt will contain the desire output

re: how to compare values from 2 different filenames?

great, it works!

but i have questions what does "more +2" (line 2) and "-ri" (line 4) use for?
just curious.. thank u very much for helping me.

re: how to compare values from 2 different filenames?

Look at f1 file....here we are interested in mobile numbers which present on second line. so we must skip first line, which is:

"Seq.No SERIAL# mobile Box Batch Area "

to skip the first line, we've used "more +2"

And, later options with grep commands are quite simple...
-r means recursive search...
-i means case insensitive...
Here we can safely avoid both of them...I am so addicted with this option, that fingers automatically types this options...

re: how to compare values from 2 different filenames?

what if i have only 1 file and the mobtel and activation date were there, but some mobtel has no activatation date (means not activated), and what i want to do is to output in a newfile all the mobtel numbers that were no activation date together with their other records such as seq no., box, area1 and finally sort using uniq. pls help thanks

re: how to compare values from 2 different filenames?

Could you please post the exact content of the file....

re: how to compare values from 2 different filenames?

this is my code:

#!/bin/sh
`more +2 f1.txt | grep "#N/A" f1.txt < sort output.txt | uniq >> output.txt`


======

these are my files and its contents:

f1.txt

code_____tel#________ place ____ activationdate
32_______ 123456______ jap ______ 20050913
33_______ 789012______ phil ______ #N/A
34_______ 987654______ thai ______ 19990112
35_______ 765433 ______ us ______
36_______ 345354 ______ la ______ #N/A
37_______ 987977 ______ us ______ 19990203

output.txt
code_____tel#________ place ____ activationdate
33_______ 789012______ phil ______ #N/A
35_______ 765433 ______ us ______
36_______ 345354 ______ la ______ #N/A
================================================== ====
PROBLEM:

i have a f1.txt file and i want to do is search all the mobile numbers that were not activated yet (do not have activation date samples are #N/A or simply a blank entry in activationdate field). now i already done "#N/A" this using grep (see my code) but obviously im not satistied finding "#N/A" only, what if the cell is empty?

second, how do i get the fieldnames of the ff so that when i look at my output.txt it automatically have these field names:

code_____tel#________ place ____ activationdate

lastly, why does f1.txt appears in every line on my output?
example :output.txt

f1.txt:33_______ 789012______ phil ______ #N/A
f1.txt:35_______ 765433 ______ us ______
f1.txt:36_______ 345354 ______ la ______ #N/A

re: how to compare values from 2 different filenames?

OK....
Try this command...

more +2 f1.txt | awk '{if( $4 == "" || $4 == "#N/A") print $1"\t"$2"\t"$3"\t"$4 }'

Here, I'm assuming that field separator in f1.txt is TAB...

I just don't understand your second problem

"second, how do i get the fieldnames of the ff so that when i look at my output.txt it automatically have these field names: "

re: how to compare values from 2 different filenames?

i want to see these column names automatically as the first row of the output.txt

code_____tel#________ place ____ activationdate

example:
code_____tel#________ place ____ activationdate----> this what i want to see in the first row
34_____9788778______mla____20080303
23_____4535354______jap____20040907

again, thank u very much for your help. :-)

re: how to compare values from 2 different filenames?

First you separate first line from f1.txt and redirect to output.txt and then run the actual command....

cat f1.txt | head -n 1 > output.txt
more -2 f1.txt | awk '{if( $4 == "" || $4 == "#N/A") print $1"\t"$2"\t"$3"\t"$4 }'

Cheers,
