I tried using services like TextCrawler , EditpadLite and more but nothing supports this large a file. Sed stream editor for filtering and transforming text is your friend. Example replaces com with net in a list of domain names and then you can pipe the output to a file.

For me none of the tools suggested here work well. Textcrawler ate all my computer's memory, SED didn't work at all, Editpad complained about memory I have't tried fart, it's only command line and maybe not very friendly.

If you want to replace text that spans multiple lines, then it becomes necessary to stop treating the input text as a collection of lines.

Since the whitespace portion of the regular expression has parentheses around it, we want to remember exactly what that whitespace was. By default, regular expressions do not let newline characters count as whitespace, so the first portion of the regular expression uses the singlelin e optio n? The approaches used so far store the entire contents of the file in memory as they replace the text in them.

This works well when replacing text in small, medium, and even moderately large files. For extremely large files for example, more than several hundred megabytes , using this much memory may burden your system and slow down your script. Jojo said on September 17, at pm.
