CONTINUAL INTEGRATION

Problem scenario
You run this command: sudo ./configure --prefix=/usr/local

But you see this:

config.status: error: in `/usr/bin/make-4.3':
config.status: error: Something went wrong bootstrapping makefile fragments
for automatic dependency tracking. Try re-running configure with the
'--disable-dependency-tracking' option to at least be able to build
the package (albeit without support for automatic dependency tracking).

What should you do?

Solution
Run this: sudo bash build.sh

Problem Scenario
You are writing a Bash command to craft AWS CLI commands. But the commands are not running with your xargs command. You created something like this:

aws s3 ls s3://bucketname/ | awk '{print "/usr/local/bin/aws s3 rm s3://bucketname/"$4}' | xargs -L 1

But it merely displays the well-crafted AWS CLI commands. You want the commands to execute.

You tried a variation but received "xargs: awscli: No such file or directory."

What should you do?

Solution

1. Find where you AWS binary is. Run this: whereis aws
2. Place the location before the "aws" command so it appears in the "print" statement of your awk command.

Rewrite the command. This example uses "tail" in case you are dealing with many files in an s3 bucket. You want to have all the command drafted after the xargs -L 1 portion. The piped output should be just the variable for the command (and flags) to run. Here is an example of a command that would work:

aws s3 ls s3://bucketname/ | tail -n 10 | awk '{print "s3://bucketname/"$4}' | xargs -L 1 aws s3 rm

Problem scenario
You are using a Mac and modifying text with TextEdit. Some text you copied is highlighted. How do you unhighlight the text?

Solution
Highlight the text that is highlighted with the mouse. There should be two pallettes at the top of the TextEdit application. These are solid-color rectangular icons to the right of the font size and to the left of the BIU (bold, italicize, underscore) icons. The righthand pallette should have a letter "a" in it. Click this pallette. Choose the option that has a red diagonal line through it.

This media.idownloadblog.com picture has an illustrative example of where to click first. You just click there then find the option with a red diagonal line on it.
