How do I select fields from a file in KShell

[Tison]

I have the following text file and I want to create a shell script that will allow some processing on the first column depending on the value of the second column ie the script logic is like this ;
FOR EACH RECORD IN THE FILE
DO
LIST THE 2ND FIELD
IF 2ND FIELD IN (aaa,bcdf,EFEFET)
DO SOME SHELL PROCESSING USING THE FIRST FIELD
FI
DONE

The file is ;
02341 JOBA_23456
01231 AGDSFFDTB
63521 AFSGHD
01122 MJGDX_12345

Hello, Tison!

I have awk solution of your problem. Please, try this awk script:


BEGIN {

list = "ABC,AFSGHD,CBA" # list of reference values
split(list,item,",&quot # split list into items

}


{
for (i in item) {
if ($2 == item) { # test value of 2nd field

print $0 # do some action
}
}
}


You can use it or get idea for shell script.

Bye!
