I thought I share this – it will probably be good complementary information for the article.

When I need to do a quick and dirty search and replace, I use biterscripting. Here are some sample scripts.

- Script to replace "ABC" with "XYZ" in file X.txt.

var str content
cat "X.txt" > $content
sal "^ABC^" "XYZ" $content > null
echo $content > "X.txt"

- Script to perform many replace operations on the same file X.txt. (I create a file C:/ReplaceList.txt in which the first field is ABC, the second field is XYZ. The fields are separated by tabs. One replace entry per line.)

var str content, searchstr, replacestr, entry, entrylist
set $wsep="\t"
cat "X.txt" > $content
cat "C:/ReplaceList.txt" > $entrylist
lex "1″ $entrylist > $entry
while ($entry "")
do
wex -p "1″ $entry > searchstr
wex -p "2″ $entry > replacestr
sal ("^"+$searchstr+"^") $replacestr $content > null
lex "1″ $entrylist > $entry
done
echo $content > "X.txt"

- Script to perform many replace operations on every .txt file in folder C:/folder. (The same C:/ReplaceList.txt file is used to specify what to replace with what.)

var str content, searchstr, replacestr, entry, entrylist, filelist, file
set $wsep="\t"
lf -n "*.txt" "C:/folder" > $filelist
while ($filelist "")
do
lex "1″ $filelist > $file
cat $file > $content
cat "C:/ReplaceList.txt" > $entrylist
lex "1″ $entrylist > $entry
while ($entry "")
do
wex -p "1″ $entry > searchstr
wex -p "2″ $entry > replacestr
sal ("^"+$searchstr+"^") $replacestr $content > null
lex "1″ $entrylist > $entry
done
echo $content > { echo $file }
done

The command we are using is sal (string alterer). Its help page is at http://www.biterscripting.com/helppages/sal.html. One can also use regular expressions with this command.

namespace FindReplaceLogLevel
{
public class Program

{
public void Main(string[] args)
{

string filePath = (@"C:\goat\goattest");
string searchText = ("goat");
string replaceText = ("mutton");
}

static public void ReplaceInFile(string filePath,string searchText,string replaceText)
{
StreamReader reader = new StreamReader(filePath);
string content = reader.ReadToEnd();
reader.Close();

content = Regex.Replace( content, searchText, replaceText );

StreamWriter writer = new StreamWriter( filePath );
writer.Write( content );
writer.Close();
}

}
}

Hope to be hearing from you.

A better solution, if you are interested, is you can send me the code, and I can publish an article with it, of course giving you full credit. It would be a great service to our readers.
