How to delete keys prefixed with hex/special characters

[Joe Leogrande]

Hi All,

I have a situation where I need to delete some old keys which look similar to below. When I attempt the delete the keys, the delete does not work.  I think I need to somehow escape the leading characters in the keys but I am not sure how to do this.

Key example:

\xAC\xED\x00\x05ur\x00\x02[B\xAC\xF3\x17\xF8\x06\x08T\xE0\x02\x00\x00xp\x00\x00\x00H{\x0A "Mode": "transit",\x0A "TransitMode": "subway",\x0A "TravelTime": 1892\x0A}

delete example:

/opt/rh/rh-redis32/root/usr/bin/redis-cli -h redis-host -p 6379 -a password --scan --pattern "*GEO_TTS*" | xargs /opt/rh/rh-redis32/root/usr/bin/redis-cli -a password del

response:

(integer) 0

Hello Joe,

The issue is with xargs' handling of backslashes - this is even documented on its man page. I was able to hack my way around it (on macOS 10.14/15) with something like the following, but YMMV depending on the OS:

redis-cli --scan --pattern "*GEO_TTS*" | sed 's/\\/\\\\/' | xargs -L 1 redis-cli -a password DEL

Cheers,
