Command Line Tricks

There are a large number of command line tricks out there for Linux.
These are some of the more special things I try to remember.

• Repeat the last command you just entered
  
  !!
• Repeat the last command you just entered thru sudo instead.
  
  sudo !!
• Use "mkdir" to create nested directories in a single command
  
  mkdir dir1/dir2/dir3/dir4
• Recursively search files starting from current directory using grep
  
  grep -R thistext *
• Download a single file via the command line
  
  wget http://www.somedomain.com/dir/file.txt
• Download entire website for off-line viewing (with all hyperlinks made local)
  
  wget --mirror -p --html-extension --convert-links http://www.somedomain.com
• Generate log file of all broken links on a given website
  
  wget --spider -o broken.log  -e robots=off wait 1 -r -p http://www.somedomain.com
• See a history list of your most used commands
  
  history|awk '{print $2}'|awk 'BEGIN {FS="|"} {print $1}'|sort|uniq -c|sort -r
• Find lost files you just saved

  find ~ -type f -mtime 0
  find ~ -type f -mtime 0 -iname '*.doc'
