arpat / remember

Super simple bash based system for remembering oneliners.

remember

• Way too simple cmdline note taker and searcher
• Blame: Arun Patel
• Generates single line entries appended to an ascii text file with the format

[# <wizzy cmdline> ## free text comment]

• If called as recollect searches instead
• use <ln -s remember.sh recollect> to softlink.
• Searching sends commands to grep.

##Example

###Install

$ cd ~
$ git clone https://github.com/arpat/remember.git
$ cd ~/bin
$ ln -s ~/remember/remember.sh remember
$ ln -s ~/remember/remember.sh recollect
$ cd ~

###Save a useful cmdline

$ sudo sysdig -p "%12user.name %6proc.pid %12proc.name %3fd.num %fd.typechar %fd.name" evt.type=open

  ...that was a great command, I want to note that down!

$ remember !!
remember sudo sysdig -p "%12user.name %6proc.pid %12proc.name %3fd.num %fd.typechar %fd.name" evt.type=open 
Remembering: sudo sysdig -p %12user.name %6proc.pid %12proc.name %3fd.num %fd.typechar %fd.name evt.type=open
What is the comment?
snoop file opens as they occur
Saving as: # sudo sysdig -p %12user.name %6proc.pid %12proc.name %3fd.num %fd.typechar %fd.name evt.type=open ## snoop file opens as they occur

###Recollecting

$ recollect 
Recollecting... Use full grep commands.
  -    -    -    -    -    -    -    -    -    -    -    -    -
  eg.   kubectl          will return any line with kubectl
  eg.  -E dpkg.*stat     will return lines with dpkg AND stat
  eg.  -e dpkg -e stat   will return lines with  dpkg OR stat
  eg.  -v \#\#           will return lines without comments
  -    -    -    -    -    -    -    -    -    -    -    -    -
What needs to be recollected?
-E sysdig.*snoop
$rememberDir is /home/apatel/remember
---
# sysdig -p "%12user.name %6proc.pid %12proc.name %3fd.num %fd.typechar %fd.name" evt.type=open ## Basic opensnoop: snoop file opens as they occur
# sysdig -p "%12user.name %6proc.pid %12proc.name %3fd.num %fd.typechar %fd.name" evt.type=open and evt.failed=true ## snoop failed file opens as they occur
---

###Usage

remember the last cmd

remember !!

remember a literal !! rather than the last cmd used using bash

remember '!!'

remember the alias cmd and prompt for a description.

 remember alias ltr="ls -ltr"

the following will fail as the shell will act on the pipe symbol:

remember ls -R | grep *.tmp

Use weak " " or strong ' ' quoting to give the desired result:

remember "ls -R | grep *.tmp"

remember without args will prompt accordingly.

The format of the saved info is a simple text file with a leading hash (to save accidental execution) and the comment on the same line separated by a double hash. Make a directory to store these files, usually ~/remember.

eg this will return all lines from all notes matching 'mdadm'

recollect mdadm

Symlink in eg ~/bin so searches any existing .list files in ~/remember -if called as recollect

ln -s remember.sh remember
ln -s remember.sh recollect

Now With Added Command Line 'tips and tricks'

I have included some of the stuff I'm working with -sysdig examples from their website, and a few gcloud ones.

To Do's

• Would be nice to specify date range of .list files for recollect, month year perhaps?
