Hi All,

The problem that I am experiencing is when the pattern is not found in file2,
print a mesg "0133333333 No Info Available". I have tried different ways but cannot
seem to find a solution.

My Code
awk 'BEGIN{printf "%10s %25s %20s %15s\n","A_NUM","DATE/TIME", "B_NUM","DURATION"}
FNR==NR {
t[$1]=$1; next
}
{if(t[$1]==$1){
if($4=="0" && ($4!="[A-Z,a-z] || $4!=\"---")){
DUR=$4
}
else
{
DUR=substr($4,1,(length($4)-1))
}
print "%10s %20s %5s %20s %10s\n",$1, substr($2,1,10), substr($2,11,18), $3, (DUR)
}
}' file1 file2


file1
======
0111111111 2006/07/01
0122222222 2006/07/01
0133333333 2006/07/01

Hi Feherke,

Thanks, but I have tried it

awk 'BEGIN{printf "%10s %25s %20s %15s\n","A_NUM","DATE/TIME", "B_NUM","DURATION"}
FNR==NR {
t[$1]=$1; next
}
{if(t[$1]==$1){Flag=1}{
if($4=="0" && ($4!="[A-Z,a-z] || $4!=\"---")){
DUR=$4
}
else
{
DUR=substr($4,1,(length($4)-1))
}
if(Flag==1){
print "%10s %20s %5s %20s %10s\n",$1, substr($2,1,10), substr($2,11,18), $3, (DUR)
}
else
{
print "Number Not Avai"
}
}' file1 file2


Result
======
A_NUM DATE/TIME B_NUM DURATION
Number Not Avai
Number Not Avai
0111111111 2006/07/03 10:01:21 0800000000 0

Maybe you can guide me to what I am doing wrong.

Thanks Again

Hi

[ol]
[li]Do not put the Flag setting and the proper operation in separate block. The [tt]if[/tt] will affect only the first.[/li]
[li]Put the flag testing at the end, so in the [tt]END[/tt] block.[/li]

awk 'BEGIN{printf "%10s %25s %20s %15s\n","A_NUM","DATE/TIME", "B_NUM","DURATION"}

Hi Feherke,

Thanks a lot. With you code I get the following error

syntax error The source line is 14.
The error context is
>>> END <<< {
awk: The statement cannot be correctly parsed.


CODE
====
awk 'BEGIN{printf "%10s %25s %20s %15s\n","A_NUM","DATE/TIME", "B_NUM","DURATION"}
FNR==NR {
t[$1]=$1; next

if($4=="0" && ($4!="[A-Z,a-z] || $4!=\"---")){
DUR=$4
}
else
{
DUR=substr($4,1,(length($4)-1))

END {
if(Flag==1){

Hi

Sorry, your styleless indenting confused me. Needs another brace ( } ) before the [tt]END[/tt].
Code: 
awk '
BEGIN {
  printf "%10s %25s %20s %15s\n","A_NUM","DATE/TIME", "B_NUM","DURATION"
}

FNR==NR {
  t[$1]=$1; next
}

{
  if (t[$1]==$1) {
    Flag=1
    if ($4=="0" && ($4!="[A-Z,a-z] || $4!=\"---")) {
      DUR=$4
    } else {
      DUR=substr($4,1,(length($4)-1))
    }
  }
}
END {
  if (Flag==1) {
    print "%10s %20s %5s %20s %10s\n",$1, substr($2,1,10), substr($2,11,18), $3, (DUR)
  } else {
    print "Number Not Avai"
  }
}
' file1 file2

Any idea

You wanted something like this ?
Code: 
awk '
BEGIN {
  fmt="%10s %25s %20s %15s\n"
  printf fmt,"A_NUM","DATE/TIME","B_NUM","DURATION"
}
FNR==NR {
  t[$1]=$1;f[$1]=0;next
}
$1 in t {
  ++f[$1];printf fmt,$1,$2,$3,$4
}
END {
  for(i in f) if(!f[i])print i" No Info Available"
}
' file1 file2

Hope This Helps, PH.

Code: 
function say( a, b, c, d )
{ printf "%10s %25s %20s %15s\n", a, b, c, d }

BEGIN { say( "A_NUM","DATE/TIME", "B_NUM","DURATION" ) }

ARGV[1] == FILENAME { a[$1] }

ARGV[2] == FILENAME  &&  $1 in a {
  b[$1]
  say( $1, $2, $3, $4 ) }

END {
  for (key in a)
    if ( ! (key in b) )
      print key, "No Info Available" }
