MaxCDN sponsors GNU Bash logo redesign

Posted by Ish

bash-orgOn 16 December 2015, Chet Ramey, the maintainer of GNU Bash announced an excited piece of news, that of new logo proposals for GNU Bash. The iconic Bash logo seen on the left was taken from tiswww.case.edu/php/chet/bash/bashtop.html.

Depending on the number of votes from the community, one of the below designs could soon sport GNU Bash.

Bash, which is a short form of writing Bourne Again Shell, is a Unix shell that comes bundled in Linux distributions and OS X. Released in 1989, GNU Bash was welcomed as a free software replacement for the Bourne shell.

Unfolding the story behind the Bash logo designs

maxcdn-logoI had this chat with Justin Dorfman, a fellow designer at MaxCDN, who had the idea of the GNU Bash logo redesign. As Justin explains, MaxCDN encourages its staff to contribute to Open Source in various ways.

Now, Justin is a huge fan of Bash, he adores stickers and realizing that GNU Bash doesn’t have an attractive logo, he wrote to Chet Ramey in September asking whether he would be okay with MaxCDN sponsoring a logo redesign. Chet showed the green light and Justin also obtained approval for resources from MaxCDN.

Justin says ProspectOne, the company behind jsDelivr and another freelancer were hired for the task. When the proposals were sent to Chet, he chose three designs by ProspectOne but could not further decide which one to select. Therefore they decided to let the final choice be that of the community and Chet sent the announcement on the bug-bash mailing list.

On the first day ~200 votes were recorded. A user by the name ‘anlar’ then posted about voting for the new bash logo on Reddit, which garnered 160 comments. At the time of writing this post over 12,000 votes were recorded, with logo no. 2 earning 79.3% of the votes.

I thank Justin who provided me an insight of the story behind the new Bash logo. Below are some of the designs that were among the initial proposals.

Chet Ramey, maintainer of GNU Bash, the popular shell that comes bundled with Linux distributions, announced earlier that he received new logo proposals for Bash. In his message on the bug-bash mail list, he invites Bash users to vote for their favorite among the three logo proposals that he received from Justin Dorfman.

Chet shared a Google form allowing people to cast their vote. I like the second proposal and voted for the same. At the time I voted the form recorded 12 responses, out of which the second logo received 11.

Customize the shell prompt

Posted by Ish

During the week I confused the hostname of a friend’s machine to be his username. He has a MacBook Pro and the shell prompt in OS X displays like:

Hostname:CurrentDirectory User$

My openSUSE laptop has the following prompt and I like it this way:

ish@coffee-bar:~>

He then asked me how to customize the shell prompt. Now, the shell prompt consists of a set of characters that appear every time the shell is ready to accept a command; like we see above. In order to customize the shell prompt with information that we want to display we need to provide some special characters to the PS1 variable (PS stands for ‘prompt string’). Additional input can be provided through PS2, PS3 etc but that’s outside the scope of this post.

We can set the prompt temporarily trying various combinations of special characters by executing something like export PS1="[t w] $ " to see a prompt like [14:52:48 ~] $.

As we can see above different sets of special characters can be used to customize the shell prompt accordingly. The table below shows various special characters that can be used to further customize the shell prompt.

Variable Description
t Prints the current time in hours, minutes and seconds.
@ Prints the current time in 12-hour am/pm format.
$ Displays the user prompt ($) or root prompt (#), depending on which user you are.
h Prints the hostname of the computer running the shell.
H Prints the full hostname (e.g localhost.localdomain).
u Prints the current username.
w Displays the full path of the current working directory
W Displays only the current working directory base name (e.g /var/log/nginx will be shown as ‘nginx’ only).

To make the shell prompt customization permanent, the value of PS1 can be added to the .bashrc file in the user’s home directory (e.g /home/username/.bashrc).
