Why does “ls -l” display the year of the (jar) file as “16:18”

terminal

I was looking through my file system and noticed that the date of mysql-v5.jar is formatted incorrectly.

~/Dev/Lib$ ls -l  
total 29128  
-rw-r-----@ 1 johndoe  staff   2256213 Mar 16  2015 guava-18.0.jar  
-rw-r--r--@ 1 johndoe  staff  11684781 Jan 30  2012 kuromoji-0.7.7.jar
-rw-r--r--@ 1 johndoe  staff    968670 May  4 16:18 mysql-v5.jar

What is going on?

(So far, all 3 jar files have worked just fine for me. I can't remember where I downloaded those files from.)

From man ls (The Long Format):

If the modification time of the file is more than 6 months in the past or future, then the year of the last modification is displayed in place of the hour and minute fields.

Or in other words: It works as designed.

Compressing server into .jar file

cd /Users/Odinulf/folderone
jar cvf myjar.jar foldertwo

For example:

/Users/ian/code/tmp [ian@Ian-Cs-MacBook-Pro] [19:13]
> jar cvf myjar.jar 8779 
added manifest
adding: 8779/(in = 0) (out= 0)(stored 0%)
adding: 8779/.DS_Store(in = 6148) (out= 355)(deflated 94%)
adding: 8779/logs/(in = 0) (out= 0)(stored 0%)
adding: 8779/logs/MasterLog.txt(in = 3044043) (out= 207357)(deflated 93%)
adding: 8779/logs/StartLog.txt(in = 6984480) (out= 685836)(deflated 90%)
/Users/ian/code/tmp [ian@Ian-Cs-MacBook-Pro] [19:13]
> ls *.jar
myjar.jar

Breaking it down, the options are:

c - create a jar file
v - be verbose when you do it
f - put the bitstream in to a file instead of standard out

Then you give it the file to put the bitstream in to. In this case myjar.jar. And then you give it a list of directories and files to put in to that jar bitstream. Relative and absolute pathing for contents is generally maintained so be careful with that.

MacOS – Why does OS X terminal need manually sourcing to display colour

The color variables should be defined before the export PS1. Now, when you call $RS on that line, that variable is empty. Try this way:

export CLICOLOR=1

# ANSI color codes
RS="\[\033[0m\]" # reset
HC="\[\033[1m\]" # hicolor
UL="\[\033[4m\]" # underline
INV="\[\033[7m\]" # inverse background and foreground
FBLK="\[\033[30m\]" # foreground black
FRED="\[\033[31m\]" # foreground red
FGRN="\[\033[32m\]" # foreground green
FYEL="\[\033[33m\]" # foreground yellow
FBLU="\[\033[34m\]" # foreground blue
FMAG="\[\033[35m\]" # foreground magenta
FCYN="\[\033[36m\]" # foreground cyan
FWHT="\[\033[37m\]" # foreground white
BBLK="\[\033[40m\]" # background black
BRED="\[\033[41m\]" # background red
BGRN="\[\033[42m\]" # background green
BYEL="\[\033[43m\]" # background yellow
BBLE="\[\033[44m\]" # background blue
BMAG="\[\033[45m\]" # background magenta
BCYN="\[\033[46m\]" # background cyan
BWHT="\[\033[47m\]" # background white

export PS1="$FBLU[\#]$RS--$RS{\t}$RS$FWHT\W$RS$FMAG@$RS$FRED\u$RS$FCYN\$$RS$FBLU>>>$RS"

alias ls="ls -l"
function cd() { builtin cd "$@" && ls -l; }
