[SOLVED] Create and save alias

danieella · 12-10-2012, 05:58 AM

Can anyone tell me how to create an alias that count the number of lines in any file and save so when you reboot, alias is still present.

Example: alias nl='wc -l'
how do i save it permanently.

Thank you

That depends a bit on the distro you are using.

.bashrc is used and will probably always work. Some distro's use .bash_aliases.

There are probably already some aliases present in either of the two files.

I used both including .bash_profile. Still not working when i reboot

Have a look at this article: Aliasing Commands

Both .bash_profile and .bashrc are mentioned.

Are you storing these aliases in the correct .bashrc/.bash_profile file? This is user specific, not global. If you want to make those aliases global then you need to store them in /etc/bash.bashrc

If that still doesn't help; please post that part of .bashrc/.bash_profile that holds the aliases.

You can setup '.bashrc' and '.bash_profile' for the user within '/home/user_name';

Code:

  sample .bash_profile;

 ~$ cat .bash_profile
 #-----------------cut-------------- 
 # .bash_profile
 #08-30-06 12:21
 #
 # Source .bashrc
 if [ -f ~/.bashrc ]; then
         . ~/.bashrc
 fi
 #-----------------cut end--------------

Code:

 sample .bashrc;
 :~$ cat .bashrc
 #-----------------cut-------------- 
 #.bashrc
 #08-30-06 12:20  
  
 # Add bin to path
 
export PATH="$PATH:/sbin:/usr/sbin:$HOME/bin"
 
#export PATH="$PATH:$HOME/bin"
 
# Dynamic resizing
 shopt -s checkwinsize
  
# Custom prompt
 #PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
 
 #08-29-06 11:40

  if [ `id -un` = root ]; then
    PS1='\[\033[1;31m\]\h:\w\$\[\033[0m\] '
  else
    PS1='\[\033[1;32m\]\h:\w\$\[\033[0m\] '
 fi
  
 #
 # Add color
 eval `dircolors -b`
  
 # User defined aliases
 alias cls='clear'
 alias clls='clear; ls'
 alias ll='ls -l'
 alias lsa='ls -A'
 alias lsg='ls | grep'
 alias lsp='ls -1 /var/log/packages/ > package-list'
 alias na='nano'
 alias web='links -g -download-dir ~/ www.google.com'

 #To clean up and cover your tracks once you log off
 #Depending on your version of BASH, you might have to use
 # the other form of this command
    trap "rm -f ~$LOGNAME/.bash_history" 0
  
 #The older KSH-style form
 #   trap 0 rm -f ~$LOGNAME/.bash_history
 #-----------------cut end--------------

The '.bashrc' and '.bash_profile' are very useful for users!
HTH!
