thanks it is working.

just wanted to know what is the use of semicolon ; for multiple gsub() used under same loop. is it mandatory to use ; after each gsub() under a given loop ?

for (i in array)
{
gsub("^"i, array[i]) ;
gsub("Configuration file for "i, "Configuration file for " array[i])
}



moreover my awk cmd is in one line and looks complex , how can i break this to multiple line ? I am using this awk command under a shell script .





Code:
#!/usr/bin/sh

fix_config()
{
  if [ -r /etc/Config ] ; then
    awk '{FS=":"} FNR==NR {array[$1]=$2; next} {FS=" "} FNR!=NR {for (i in array) {gsub("^"i, array[i]) gsub("Test "i, "Test "array[i]) ; {if(toupper($0) ~ toupper(i)) {gsub("! Configuration for "toupper(i), "! Configuration for " toupper(array[i]))}}}} !/This is my conf/  1'  /etc/Mapping  /etc/Config  > Config.bk
  fi
}


fix_config



Thanks.........






thanks...

toupper

TOUPPER(3)						   BSD Library Functions Manual 						TOUPPER(3)

NAME

     toupper, toupper_l -- lower case to upper case letter conversion

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <ctype.h>

     int
     toupper(int c);

     #include <ctype.h>
     #include <xlocale.h>

     int
     toupper_l(int c, locale_t loc);

DESCRIPTION

     The toupper() function converts a lower-case letter to the corresponding upper-case letter.  The argument must be representable as an
     unsigned char or the value of EOF.

     Although the toupper() function uses the current locale, the toupper_l() function may be passed a locale directly. See xlocale(3) for more
     information.

RETURN VALUES

     If the argument is a lower-case letter, the toupper() function returns the corresponding upper-case letter if there is one; otherwise, the
     argument is returned unchanged.

COMPATIBILITY

     The 4.4BSD extension of accepting arguments outside of the range of the unsigned char type in locales with large character sets is considered
     obsolete and may not be supported in future releases.  The towupper() function should be used instead.

SEE ALSO

     ctype(3), isupper(3), towupper(3), xlocale(3)

STANDARDS

     The toupper() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
