Reflashing Cisco Switch

(2960 or equivalent without USB etc) over serial

Kinda used to having modern equipment with USB etc, unbricking this was harder than expected and tftpd64 and equivalents weren't proving reliable for me. Hope this helps others.

Put the output from a dialog box into a bash variable:

termux-dialog outputs data in json format so we need to parse that. One way is to use jq which needs to be installed: apt install jq -y

Then because we're going to pipe the output into jq we'll need to enclose everything in double quotes before assiging to a variable. This is is a good example:

myvariable="$(termux-dialog -t "Please enter some text" | jq '.text' -r)"
