Hi all,
I have two parameter blocks in a configuration file, file1.conf.
First parameter block starts with PWAT-PARM1 and
ends with END PWAT-PARM1.

Second parameter block starts with PWAT-PARM2 and
ends with END PWAT-PARM2 (please see below in file1.conf).
file1.conf is fixed width columns and numeric values are written in fortran format.

I don't know how to update numeric values in file1.conf from two different files, file2.txt and file3.txt for each iteration.
Thus, numeric values in the first parameter block (PWAT-PARM1) should be updated from file2.txt
and, numeric values in the second parameter block (PWAT-PARM2) should be updated from file3.txt

<file1.conf>

Try this:

awk 'BEGIN{getline v1 < "file2.txt";getline v2 < "file3.txt"}
/PWAT-PARM1/{print;getline;print;getline;print;print v1;next}
/PWAT-PARM2/{print;getline;print;getline;print;print v2;next}
{print}
' file1

Hi Franklin,

Thanks to you, I am almost got the solution, but I don't know how to loop in getline from two files. Only first line from file2.txt and file3.txt is updated in file.conf. For next iteration, file.conf should be updated with second line from these two files.

Jae,

awk 'BEGIN{getline v1 < "file2.txt";getline v2 < "file3.txt"}
/PWAT-PARM3/{print;getline;print;getline;print;getline
        if (match($0,match(v1,$0))) {
                        print v1;
                        getline
                } else {
                        # do some stuff here
                        print
                }
			next
			}
/PWAT-PARM4/{print;getline;print;getline;print;getline
        if (match($0,match(v2,$0))) {
                        print v2;
                        getline
                } else {
                        # do some stuff here
                        print
                }
			next
			}
{print}
' file1

why does it have to be in separate iterations?
why not grab all the lines from file1.txt and file2.txt immediately?


oh and another question:

why would PARM1 match-up with file2.txt?
why not match the numbers?

anyways... the problem is 2-fold. I think what you want is a bunch of
different configuration files in order to do some serious testing.

I don't believe you even need an original configuration file.

So, if I'm understanding you correctly:

You have a list of 2 different sets of data that are required for a single configuration.
Each configuration should contain one line from each set of data.
So in the end, you should have as many configuration files as you have lines of data.

To that end, here's the solution:

#----------------------------------------------------------------------#
# Internal field separator to pipe.                                    #
#----------------------------------------------------------------------#
IFS="|"

#----------------------------------------------------------------------#
# Counter for file name.                                               #
#----------------------------------------------------------------------#
num=1

#----------------------------------------------------------------------#
# Paste parameter files together with pipe symbol.                     #
#----------------------------------------------------------------------#
paste -d\| file2.txt file3.txt |
while read a b ; do

#----------------------------------------------------------------------#
# Create numbered configuration files.                                 #
#----------------------------------------------------------------------#
  cat << EOF > file$num.conf
PWAT-PARM1
*** < PLS> PETMAX PETMIN INFEXP INFILD DEEPFR BASETP AGWETP
*** x - x (deg F) (deg F)
$a
END PWAT-PARM1

PWAT-PARM2
*** <PLS > CEPSC UZSN NSUR INTFW IRC LZETP
*** x - x (in) (in) (1/day)
$b
END PWAT-PARM2
EOF

#----------------------------------------------------------------------#
# Next number...                                                       #
#----------------------------------------------------------------------#
  (( num += 1 ))

done

Hi quirkasaurus,

Your code is also attractive and looks fine. But, I don't know why I got error message at the end of file.
"./file.sh: line 35: syntax error: unexpected end of file"

Any suggestions?

Jae

did you miss the "done" command when copying and pasting?

if not.... post of all the script here and we'll see what's up.
