Emergency UNIX and Linux Support

Dear Unix experts

Moved from "Shell Programming and Scripting "
I want to define a variable which contains dynmic and static part, daynamic part is the first field.

Sample of data

Code:

dddd aaaa sssss 12345
ssss 2323 234234 4242
dddd 3223 34234 54353
ssss 24234 3434 42342
dddd rwrw 423423 werwer

Code:

Code:

nawk 'BEGIN {FS=" "}{ $1"_subs"=$1"_subs"+1}END {print dddd_subs}'

it should give me 3

but it gives me error "nawk: syntax error at source line 1
context is

Code:

BEGIN {FS=" "}{ >>> $1"_"subs= <<< $1"_"subs+1}
nawk: illegal statement at source line 1"

Can you please help ?
Many thanks in advance

I also tried

Code:

Code:

nawk 'BEGIN {FS=" ";diff[$2]=2}{ subs[$1]=+1}END {print subs[dddd], diff [rwrw]}

, Also error...

Can any one advise how to do it in any of the ways above

Could you elaborate more on how the expected output of 3 should be calculated?

Thread reopened because in the Emergency forum.

Try this:

Code:

nawk 'BEGIN {FS=" "} {subs[$1]++} END {for (i in subs) print i, subs[i]}'

Your last version uses a field variable, $2, in a BEGIN statement.
This is not valid because when the BEGIN statement executes no
data has been read, therefore there is no $2 field variable.
