Try this command to see if it works for you in large file environments. If you can master this technique it can save time creating editing and transferring files that you are collaborating on with others. The diff command is also useful when you just want to know if two copies of the same file are identical or not. If you find yourself with multiple copies of similar files diff is a fast and easy way to find out if they are identical. If the files are not identical you will be able to see what changes have been made between them. No output produced by diff means that there are no differences between the files. The patch command is also useful. It can be thought of as phase two of using the diff command. Now that you have your template update and new patchfile you can use the patch with the file you want to fix. This can be seen as patch template.txt patch.txt patching file template.txt The patch command will automatically update and patch the file named template. You applied the patch to the template and that was it. You can now use cat or more and view the files you created to see what the differences are between them. Always remember to keep a copy of your template file around. In this example the patch was applied directly to the template file and the template file was updated. If all further patches are created from the updated file no problem however if patches are created based on the original template then the template.txt can no longer be patched. Now you should be comfortable with most of the common Unix file management techniques such as learning how to create read edit move and copy files. You should also feel comfortable using fancy little tricks such as reading the head or tail of a file or using grep for its contents. We have covered a lot about file management and you should be very proud of yourself if you nailed it. These 10-minute lessons are meant to show you .
