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...
