use the more command to view the file page by page. if you want to find some text in the file or do something with the file, use awk.

Granted I've never tried a 4GB file, I'd imagine a more sophisticated program should still be able to open it. I've opened several hundred meg to 1GB files in Textpad, my favorite Windows text editor.

Just curious what type of data is consuming 4GB?

Nice suggestion.

@OP , if you want to view  a large file in *nix, you can use vim. from the vim faq

Maximum file size      2147483647 bytes (2 Gbyte) when a long integer is
            32 bits.  Much more for 64 bit longs.  Also limited
            by available disk space for the |swap-file|.

Dear All,

there's an OpenSource project allowing the display of large files. It is written in Java language: you can find it at http://sourceforge.net/projects/largefileviewer/

There's a user manual.

I tried it with a 1.8GB text file without any problem but you have to use parameter -XmxMEMORY_SIZEm when you launch the program. For instance:

java -Xmx700m -jar LargeFileViewer.jar BigFile.txt

I never tried with a 4GB file size, in this case the -Xmx700m must be replaced by a bigger value.

I heard about some limitations with the JVM heap space (2GB, but must be checked).

Hope this will help you.


Best Regards.
