It ll split each page in your pdf file , into a new pdf file and report info on doc_data.txt
Takes file (text.txt), removes BOM from it, and outputs the result to a new file (newFile.txt). BOM is "Byte Order Mark" ([http://en.wikipedia.org/wiki/Byte_order_mark]), an invisible, non-breaking, zero-length character.

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

Good if only you have access to host1 and host2, but they have no access to your host (so ncat won't work) and they have no direct access to each other.
This will send a test print job to a networked printer.
if you need a quick way of printing out all the packages that contain classes this command will print the directory structure and replace '/' with '.'
