## Generate MD5 Checksum for every file in a specific path
$ find <path> -type f -exec md5sum {} + > sums.md5

## Removing sensitive data from a repository
# source: https://help.github.com/articles/removing-sensitive-data-from-a-repository/

# these arguments will:
#
# force Git to process, but not check out, the entire history of every branch and tag
# remove the specified file, as well as any empty commits generated as a result
# overwrite your existing tags
#
# can only do one file at a time

## How to pull after a forced git push
$ git fetch origin
$ git reset --hard origin/master # be aware; this will destroy local work that does not ywt exist in the repository

## Find all files containing specific text
$ grep -rnw '/path/to/somewhere/' -e "pattern"

# (path/ must absolute!)
# -r or -R is recursive,
# -n is line number, and
# -w stands for match the whole word.
# -l (lower-case L) can be added to just give the file name of matching files.

# along with these, --exclude, --include, --exclude-dir or --include-dir flags could be used for efficient searching:

## Add missing file to previous commit
# 1. stage the file you forgot to add to the previous commit
# 2. run the below mentiond command

$ git commit --amend –C HEAD

## delete files with the current directory as the 'root' directory based on a wildcard
# find every file in the current directory recursively based on a wildcard.

$ find . -name '._*' -type f -delete

## order directory content by size
# MAC
$ du -sh /directory/to/search/*/ | sort -n -r

# UNIX
$ du -hc --max-depth=1 . | sort -n -r

# du:
# -s, --summarize             Display only a total for each argument.
# -h, --human-readable        Append a size letter such as `M' for megabytes to each size.
#                             Powers of 1024 are used, not 1000; `M' stands for 1,048,576 bytes

## SeLinux
# SeLinux doesn't like if files are moved from one place to another.
# if were to copy the file than SeLinux will have no problem with it whatsoever.
# If you do run into issues;

// will give you overview of all SeLinux permissions
// files need to match `httpd_sys_content_t`
$ ls -lZ

// I'm not that familiar with SeLinux BUT here is way to fix the permission for a file
$ mv <filename> /tmp

## locate update file location database
# update the file database
$ sudo /usr/libexec/locate.updatedb

# If you would like to have the command updatedb to get a more consistent behavior between your Linux and Mac environment you can symlink it to /usr/local/bin.
$ ln -s /usr/libexec/locate.updatedb /usr/local/bin/updatedb
