1. ======= useful command ==========

• fzf is a general-purpose command-line fuzzy finder

• find all files containing specific text

  • Basic

    grep -rnw '/path/to/somewhere/' -e 'pattern'

  • This will only search through those files which have .c or .h extensions:

    grep --include=\*.{c,h} -rnw '/path/to/somewhere/' -e "pattern"

  • This will exclude searching all the files ending with .o extension:

    grep --exclude=\*.o -rnw '/path/to/somewhere/' -e "pattern"

  • For directories it’s possible to exclude one or more directories using the --exclude-dir parameter. For example, this will exclude the dirs dir1/, dir2/ and all of them matching *.dst/:

    grep --exclude-dir={dir1,dir2,*.dst} -rnw '/path/to/somewhere/' -e "pattern"

2. ======= git ==========

$ git clean -fd
git clean -f
git apply --whitespace=nowarn  ~/br_lge_extensions.patch
git reset --hard HEAD
git clone --recursive

3. Remote develop

• Use ssh without password

  $ssh-keygen -t rsa
  $ssh-copy-id -i ~/.ssh/id_rsa.pub {user}@{host}

• Download a single file from a remote ftp server to your machine:

  $sftp {user}@{host}:{remoteFileName} {localFileName}

• Upload a single file from your machine to a remote ftp server:

  $sftp {user}@{host}:{remote_dir} <<< $'put {local_file_path}'
