Hi,

I am using the following script to search and replace the deprecated functions in a file with the newer ones.

  5 for strFile in `ls deprecated_functions_search_and_replace.txt `
  6 do
  7     sed "s/ereg_replace[^\(]*(\([^,]*\),/preg_replace\1('#'.\2.'#',/g"  $strFile > temp_file
  8     mv $strFile $strFile".bakup"
  9     mv temp_file $strFile
 10
 11     sed "s/eregi[^\(]*(\([^,]*\),/preg_match\1('#'.\2.'#i',/g" $strFile > temp_file
 12     mv $strFile $strFile".bakup"
 13     mv temp_file $strFile
 14
 15     sed "s/ereg[^\(]*(\([^,]*\),/preg_match\1('#'.\2.'#',/g" $strFile > temp_file
 16     mv $strFile $strFile".bakup"
 17     mv temp_file $strFile
 18
 19     sed "s/split[^\(]*(\([^,]*\),/preg_split\1('#'.\2.'#',/g" $strFile > temp_file
 20     mv $strFile $strFile".bakup"
 21     mv temp_file $strFile
 22
 23     sed "s/mysql_escape_string/mysql_real_escape_string/g" $strFile > temp_file
 24     mv $strFile $strFile".bakup"
 25     mv temp_file $strFile
 26
 27     sed "s/set_magic_quotes_runtime(0)/\/\/set_magic_quotes_runtime(0)/g" $strFile > temp_file
 28     mv $strFile $strFile".bakup"
 29     mv temp_file $strFile
 30
 31     sed "s/ini_get('safe_mode')/false/g" $strFile > temp_file
 32     mv $strFile $strFile".bakup"
 33     mv temp_file $strFile
 34
 35     sed "s/session_register('\(.*\)')/$_SESSION['\1']=$\1/g" $strFile > temp_file
 36     mv $strFile $strFile".bakup"
 37     mv temp_file $strFile
 38
 39     sed "s/session_unregister('\(.*\)')/$_SESSION['\1']=''/g" $strFile > temp_file
 40     mv $strFile $strFile".bakup"
 41     mv temp_file $strFile
 42
 43 done

However, when I run this script I am getting an error saying:

sed: -e expression #1, char 60: invalid reference \2 on `s' command's RHS
sed: -e expression #1, char 52: invalid reference \2 on `s' command's RHS
sed: -e expression #1, char 50: invalid reference \2 on `s' command's RHS
sed: -e expression #1, char 51: invalid reference \2 on `s' command's RHS

I am unable to figure out whats going wrong. Someone please help me. Regards.
