AWK scripts..

[ethnicme]

I have a problem with awk..

Is it possible to create a script in AWK that reads that input of a user from a keyboard..

Something like:
Prompts the user for some string input and stores this string into a variable which will be use in the process.. ? ..

Hi, ethnicme.

Yes it is possible, although it may not be obvious. One way is illustrated here:

#!/usr/bin/awk -f
#!/usr/bin/nawk -f
#!/usr/bin/mawk -f
#!/usr/bin/gawk -f

# @(#) a4       Demonstrate awk writing to, reading from terminal.
# Note that the "-f" is required in the sh-bang line.
# Use: ./a4 file  -or-  ./a4 /dev/null
# Verified with awk, nawk, gawk, mawk.

BEGIN   { print "System " ARGV[0] ": enter your name" > "/dev/tty"
                getline name < "/dev/tty"
        }
        { print $0 }
END     { print "I read your name as: " name > "/dev/tty" }

When this is run with an existing trivial file:

% ./a4 data1
System awk: enter your name
drl
Hello, world.
I read your name as: drl

Best wishes ... cheers, drl
