Convert Mac to Unix line endings in VI

to shell mac vi unix text by danb on Oct 08, 2007 1 Comments
If you open a text file in VI and see one big line with lots of '^M' where the line endings are supposed to be, use this command to fix it.
(Enter the the ^M by hitting ctrl-v and then the return key.)

:1,$s/^M/\r/g

Human Readable ls and df commands

to osx bash unix linux commandline terminal by danb on Sep 04, 2007 1 Comments
Simple but useful to know...

To get a ls (file list) or df (disk free) to show in K,M or G instead of *huge* numbers of bytes without commas, use the -h flag. 

ls -lh
df -h

Get all files in ftp server directory using WGET

to shell osx mac unix ftp wget by danb on Jul 30, 2007
It's a PITA to recursively get all files in a directory using ftp. Instead use wget.

wget -r ftp://account_name:password@example.com/directoryname

Quick and easy way to look up a domain name given an IP address.

dig -x 17.254.3.183
