Check These Out
You can set the previous bash command as the terminal title by this command.
Explanation:
-trap assigns a command to execute at a given bash signal.
-in the $BASH_COMMAND you find the last command
-you can set the terminal title with the escape sequence: \e]0;this is the title\007
-to let the echo care about the backslashes give the -e to it
Since trap is a built in bash command you find more informatin in 'man bash'for more

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
when using named pipes only one reader is given the output by default. Also, most commands piped to by grep use a buffer which save output until tail -f finishes, which is not convenient. Here, using a combination of tee, sub-processes and the --line-buffered switch in grep we can workaround the problem.
Working with log files that contains variable length messages wrapped between open and close tags it may be useful to filter the messages upon a keyword.
This works fine with GNU sed version 4.2 or higher, so pay attention to some unix distros (solaris, hp-ux, etc.).
Linux should be ok.

$ /lib/ld-linux.so.2
is the runtime linker/loader for ELF binaries on Linux.
=(cmd) is a zsh trick to take the output for the command "inside" it and save it to a temporary file.
$ echo -e 'blah' | gcc -x c -o /dev/stdout -
pipes the C source to gcc. -x c tells gcc that it's compiling C (which is required if it's reading from a pipe). -o /dev/stdout - tells it to write the binary to standard output and read the source from standard input.
because of the the =() thing, the compiled output is stashed in a tempfile, which the loader then runs and executes, and the shell tosses the tempfile away immediately after running it.
Change files case, without modify directories, recursively.
