+my dotfiles for Carbs Linux someday I promise). I will
+also be merging my useless utilities that are currently

+Dumb password manager with absolutely no fancy features. By
+that I mean,
+
+* No password generation
+* No git integration
+* No questions asked
+* No grepping/finding passwords
+* No clipboard support
+* No tree view
+* Does not ask for password input (reads from stdin)
+
+Currently 34 SLOC. Supports adding/deleting/listing/showing
+passwords. I don't intend on implementing any more features.
+You can wrap this script with something other to make use of
+it.
+
+To install run, as root if necessary
+
+ make -C pm install
+
+You really do think that asking for password for twice blah
+blah is a really important feature? Okay, then add a function
+to your shellrc/profile like this.
+
+ pmask() {
+ [ "$1" ] || return 1
+ printf 'Enter your password: '
+ read pass
+ printf 'Enter your password again: '
+ read pass2
+ if [ "$pass" = "$pass2" ] ; then
+ printf '%s' "$pass" | pm a "$1"
+ else
+ printf "Passwords don't match\n"
+ return 1
+ fi
+ }
+
+You want to copy to clipboard? That's easy! You just need
+to do a `pm s passname | xclip -sel c`. You can still make
+it a function by doing this
+
+ copypass() {
+ [ "$1" ] || return 1
+ pm s "$1" | xclip -sel c
+ }
+
+The whole rationale is that you can already do that with simple
+commands. Why complicate (and possibly break) things by introducing
+them into a single script? If you want some function that is
+a must for you, implement it yourself with some script or
+a shell function. This way, it works just as you intended it.
