## perl replace
perl -i -p -e 's/search/replace/' filename;

## chmod

find <folder> -type d -exec chmod 755 {} \;
find <folder> -type f -exec chmod 644 {} \;

## git revert
Try this first:

git checkout master
(If you're on a different branch than master, use the branch name there instead.)

If that doesn't work, try...

For a single file:

git checkout HEAD /path/to/file

## Find and replace
find ./ -type f -exec sed -i 's/find/replace/g' {} \;

## python test
Run all tests
```python
#file __init__.py
def load_tests(loader, standard_tests, pattern):
    # top level directory cached on loader instance
    this_dir = os.path.dirname(__file__) + '/tests'
    package_tests = loader.discover(start_dir=this_dir, pattern=pattern)
    standard_tests.addTests(package_tests)
    return standard_tests
```

What you're seeing is probably because the server serving the static files is using the "sendfile()" syscall, which is broken with the VirtualBox file system. You need to disable sendfile() usage in your server. For Apache:

EnableSendfile off

And for nginx:

sendfile off;

## find and size
# find old files and calculate their size in Mb
find ./logs/* -type f -mtime +180 -exec du -ks {} \; | cut -f1 | awk '{total=total+$1}END{print total/1024}'

## Replace in big file
perl -e 'BEGIN{$/=\32768}' -pe "s/a/b/g" < one-line-250-mb.txt

## extract_phar.sh
#!/usr/bin/env bash

#extract phar
phar extract -f php_util.phar extracted

#how to check is in phar
#if (strpos(__DIR__, 'phar://') === 0) {}

    SSH Broken Pipe fix

Source
To fix it, on your mac do:
emacs (or vim/vi/nano/etc) ~/.ssh/config
And then, write this:

	find <folder> -type d -exec chmod 755 {} \;
	find <folder> -type f -exec chmod 644 {} \;
	Try this first:

	git checkout master
	(If you're on a different branch than master, use the branch name there instead.)

	If that doesn't work, try...

	For a single file:

	git checkout HEAD /path/to/file
	Run all tests
	```python
	#file __init__.py
	def load_tests(loader, standard_tests, pattern):
	# top level directory cached on loader instance
	this_dir = os.path.dirname(__file__) + '/tests'
	package_tests = loader.discover(start_dir=this_dir, pattern=pattern)
	standard_tests.addTests(package_tests)
	return standard_tests
