How to split a file into smaller chunks?

You may want to upload a 100GB file over an unstable network, or feed your scripts smaller inputs to load in RAM. In both cases, just splitting your file into smaller chunks is an easy solution.

Great news is Unix/Linux systems have the split utility already installed. And using it is simple as pie:

Cut a binary file into chunks of X bytes:

split -b X bigfile.avi

How to output a range of lines from a file?

Easy enough with sed:

sed -n	123,230p filename

This will output filename content, from line 123 to line 230, inclusives. Notice the p letter after the last line number, this is what instruct sed to print to stdout.

let regex;

/* matching a specific string */
regex = /hello/; // looks for the string between the forward slashes (case-sensitive)... matches "hello", "hello123", "123hello123", "123hello"; doesn't match for "hell0", "Hello" 
regex = /hello/i; // looks for the string between the forward slashes (case-insensitive)... matches "hello", "HelLo", "123HelLO"
regex = /hello/g; // looks for multiple occurrences of string between the forward slashes...

/* wildcards */
regex = /h.llo/; // the "." matches any one character other than a new line character... matches "hello", "hallo" but not "h\nllo"
regex = /h.*llo/; // the "*" matches any character(s) zero or more times... matches "hello", "heeeeeello", "hllo", "hwarwareallo"

How to track large files (database, PSD, bin) in Git?

Sometimes you have PSD or a small-ish SQLite file you’d like to track with Git. The problem is Git is bad at tracking changes in big binary files by default. With Git Large File Storage (LFS) you can replace these large files with text pointers while storing the file contents on a remote server. Both GitHub and BitBucket support it. Here is how to get started:

1. Install Git LFS extension (Mac here):

brew install git-lfs

How to change your commit messages in Git?

At some point you’ll find yourself in a situation where you need edit a commit message. That commit might already be pushed or not, be the most recent or burried below 10 other commits, but fear not, git has your back 🙂.

Not pushed + most recent commit:

git commit --amend

This will open your $EDITOR and let you change the message. Continue with your usual git push origin master.
