How can I extract the base64 value shown below? I was trying to use something like awk {'print $14'}, but this doesn't work because the entire output is first item. If I decode the base64 value first, then I'm able to use awk {'print $14'} to eventually obtain the value that I need.

$ curl -s --request GET http://10.0.10.10:8500/v1/kv/w-key-value

[{"LockIndex":0,"Key":"w-key-value","Flags":0,"Value":"WyAgeyAgICBDcmVhdGVJbmRleDogMTAwLCAgICBNb2RpZnlJbmRleDogMjAwLCAgICBMb2NrSW5kZXg6IDIwMCwgICAgS2V5OiB6aXAsICAgIEZsYWdzOiAwLCAgICBWYWx1ZTogMSAgICBTZXNzaW9uOiBhZGY0MjM4YS04ODJiLTlkZGMtNGE5ZC01YjY3NThlNDE1OWUgIH1d","CreateIndex":4080,"ModifyIndex":4080}]

  • With GNU grep: grep -Po '"Value":"\K[^"]*' file or with GNU sed: sed 's/,/\n/g' file | sed -nE 's/^"Value":"(.*)"/\1/p' Commented May 14, 2018 at 1:55
