Java "sed" substitute command

Something like this will get you started:

String line;
// Read the file
try (BufferedReader input = new BufferedReader(new FileReader(file))) {
    while ((line = input.readLine()) != null) {
         // Do the string replacement
         line = line.replace("Q3A01RAD","MPM01   ");

         // Print out the result
         System.our.println(line) ;
    }
}

Select allOpen in new window

Something like this will get you started:

In point of fact, you posted something implementing

 's/Q3A01RAD/MPM01   /g'

Select allOpen in new window

To implement the given pattern, you'd need String.replaceFirst

Good catch CEHJ!

Jim Cakalic -- I like the idea of using unix4j. However, I'm trying to figure out how to get it in my RedHat Eclipse IDE. Is there a compiled jar out there somewhere that I can add to my build path to get access to the functionality and have intellesense to help me formulate the syntax?

Would you trust this site to get the unix4j jars?
http://www.java2s.com/Code/Jar/u/unix4j.htm

I would assume I would just add those to my class path...

Or, maybe this one?
http://grepcode.com/snapshot/repo1.maven.org/maven2/org.unix4j/unix4j-command/0.3/

Ok. I figured out how to use unix4j in my java code. Unfortunately, the file that I am attempting to use as input is a BINARY file.  Command-line sed worked on my binary file, but the unix4j routine seems to have trouble with it (the binary file got larger/corrupted. Any ideas?

sed is normally used on text files (it works line-wise) so the Java implementation might not expect to have to be able to work with binary files

CEHJ -- yes, I am very lucky that sed works on these particular binary files that I apply it on.

I'm not sure you can rely on the continuance of that
