Uptime

A shell program that reads a list of URL's line by line and checks their connectivity/status with curl. The aim of this tool is to promote network health and awareness with a little customization of the output and reports possible at some point.

TODO:

1. Make output of shell script tabular so it can be consumed by other programs more effectively
2. Figure out a way to make two instances of the script talk to each other to get connectivity from two points to compare and reach a combined result.

Usage (Development)

1. Put your URL's in urls.txt;

2. Get results printed to standard output

sh uptime.sh

Usage (Master branch)

1. Put your URL's in urls.txt;

2. Generate a temporary report:

sh uptime.sh

Write report to a new file:

sh uptime.sh -a

Write a crude formatted file by success/failure:

sh uptime.sh -f

Progress

Small batch of commits in March - picking it back up in May!

• Passed initial Shellcheck
• Tested on a collection of URLs of the world's most visited sites. Most all were up as you would expect.

Development:

Just a few shellcheck errors to follow up on after paring it down.

$ shellcheck uptime.sh 
In uptime.sh line 20:
   curl=$(curl -Is --max-time 15 "$line");
   ^--^ SC2034: curl appears unused. Verify use (or export if used externally).
In uptime.sh line 23:
     printf "$line $res No";
            ^-------------^ SC2059: Don't use variables in the printf format string. Use printf '..%s..' "$foo".

Goals

• Write results in crude/basic tabular format for consumption by other programs
• Improve reliability and accuracy
