Short list of all ip.
Shows even the newly supported multiple ip address on the same interface (see eth1).
For ipv6 use -6
Replace 'csv_file.csv' with your filename.
I learned a few things reading this command. But I did run into a few issues:
1. On systems that don't use GNU echo (e.g. macOS 10.14.5 Mojave), the e option may not be supported. In this case ANSI escape codes will echoed as text and the terminal will not flash, like this:
\e[?5h\e[38;5;1m A L E R T Thu Jun 20 16:31:29 PDT 2019
2. Since the read command strips\ignores leading backslashes, if a user types the backslash character once in the loop, it will not break. Typing backslash twice in a loop will break as expected.
3. The foreground color is set to red (\e[38;5;1m) on every loop. This could be set once before we call while, and then reset once when the loop breaks.
4. Instead of resetting the foreground color when it breaks, the video mode is set back to normal (\e[?5l). This has the effect of leaving the terminal text red until it is manually reset.
The alternative I'm proposing here addresses these issues. I tested it on macOS and Arch Linux.
There are some environments that use this value for password and account expiration. It's helpful to be able to quickly determine the number of days since the Unix epoch (dse) when working directly with the configuration files as an administrator.
use to execute a block of code only if $var is numeric
Allow to read password in a script without showing the password inserted by the user
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token.
This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use:
`awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'`
You must adapt the command line to include:
* $MFA_IDis ARN of the virtual MFA or serial number of the physical one
* TTL for the credentials
