If you are like me, typing CD command again and again would quickly get tiresome and wonder there must be a better way to do it.

I have done some searching on Google and this forum. The results I get (using alias, CDPATH or PUSHD) do not satisfy me completely, so I decide to do it my way.
Fortunately, I do not need to reinvent the wheel. Linux already provides us with great tools, and all I need to do are just to glue them together.

Here is how:
Step1: Look for the directory using FIND command.
Step2: Filter out the results with GREP.
Final step: CD the directory.

Bash code:

Code:

  #!/bin/bash
  # File name: “sc” stands for simple cd.
  # Functionalities: Simple way to navigate directories.
  # Created by: IKE0000
  # Created date: 2012/4/27
     
# If only one parameter is provided, then sc works just like CD command
    if (($#<2))
then      cd $1;
  else
  # Define frequently used directories here. 
  # I borrow the concept from CDPATH. 
  # For example: 
  # “o” for ORACLE
  # “a” for Apache
      if [[ $1 == "o" ]]
      then
          search="/u01";
      elif [[ $1 == "a" ]]
      then
          search="/etc/httpd";
      else
          search="$1";
      fi;
  
  IFS="/";
      array=($2);
      name1=${array[0]};
      name2=${array[1]};
      unset IFS
  
  # Build up the search command 
      if (( ${#array[@]} < 2 ))
      then
          cmd="find $search -name $name1 -type d"
  else
   # We need to filter out the result in backward order
          cmd="find $search -name $name2 -type d | grep $name1"
      fi;
  
      cd $(eval $cmd)
  fi;
  
  echo -e "\e[1;34m" $(pwd) "\E[0m"

Configuration:
Step1: Change file permission to make it available to other users:

Code:

chmod u+x sc.sh

Step2: Copy sc.sh to /bin/sc. Or if you don't have the permission to do that, you can add the folder in which sc.sh is located to PATH variable in .bash_profile.
Step3: Add an alias in .bash_profile, this little dot is required change your current directory:

Code:

alias sc=”. sc”  

Usage:
sc /etc works just like CD command

sc /etc *scripts will take you to :
/etc/sysconfig/network-scripts

sc o udum* will take you to:
/u01/app/oracle/admin/orcl/udump

sc o euser/admin will take you to:
/u01/app/oracle/oracle/product/10.2.0/db_2/oc4j/j2ee/oc4j_applications/applications/em/em/euser/admin


Hope it will be useful to you.
