lpass is a lastpass cli client with a lot of subcommands and options to do a lot of things which are hard to remember. Based on my day-to-day usage of it, I created a set of bash functions to simplify the usage. An up-to-date version of the functions can be found here.
There are four functions:
lpget() to get the password of a given site.
$ lpget google.com copied google.com secret to clipboard
lpuser() to get the username of a given site.
$ lpget google.com
lpsearch() to perform grep on all the sites in an account.
$ lpsearch google.com google.com [id:12345678] google.com-work [id:987654]
lpsg() to perform search and get password of a given site.
$ lpsg google.com copied google.com secret to clipboard
When there are multiple sites with similar names:
$ lpsg google.com 2 copied google.com-work secret to clipboard
lpsearch to search and copy the required secret.
