There are certain files created by particular editors, IDEs, operating systems, etc., that do not belong in a repository. But adding system-specific files to the repo's .gitignore is considered a poor practice. This file should only exclude files and directories that are a part of the package that should not be versioned (such as the node_modules directory) as well as files that are generated (and regenerated) as artifacts of a build process.

All other files should be in your own global gitignore file. Create a file called .gitignore in your home directory and add anything you want to ignore. You then need to tell git where your global gitignore file is.

Mac

git config --global core.excludesfile ~/.gitignore

Windows

git config --global core.excludesfile %USERPROFILE%\.gitignore

Checking logs on multiple remote server

for host in hd1pxx2{1..6}lx; do echo $host; ssh $host "grep \"FATAL\" /home/bmadmin/bmsPRD2012/log/*_website_activity.log | wc -l"; done

How do I find all files containing specific text on Linux?

grep -rnw '/path/to/somewhere/' -e 'pattern'
-r or -R is recursive,

ScalaDays NYC (2016)

KeyNote:

• Scalajs is matured enough to be used for Production systems.
• Macros, procedual syntax and early initializers are gone.
• 2.12 introduces effect system and meta programming.
• Dotty the new compiler - faster than current scala.
• Scala will be forked into multiple projects - core, platform etc etc in 2.13.
• Scala Native got opensourced - very early to adopt but something cool to work for in near future.
