=== Install essential tools === | |||
<pre> | |||
apt-get install bash coreutils-gnu grep-gnu wget vim | |||
</pre> | |||
Change shell in /etc/passwd to bash: | |||
<pre> | |||
root:x:0:0:root:/root:/bin/bash | |||
user:!:29999:29999::/home/user:/bin/bash | |||
</pre> | |||
<i>NOTE:</i> Maemo ignores [http://de.wikipedia.org/wiki/Shebang shebangs] for shells and always executes shell scripts in busybox. You need to pass the script explicitly to any other shell: | |||
<pre> | |||
bash ./test.sh | |||
</pre> | |||
<b>WARNING:</b> Don't try to relink /bin/sh to /bin/bash. You system won't boot and you will have to reflash the device. | |||
<br> | |||
<i>NOTE:</i> Gnu coreutils and gnu grep are prefixed with the letter 'g'. Therefore you need to call <pre style="display: inline; padding: 2px">/usr/bin/gls</pre> to use gnu ls. For some third party scripts/builds to work properly you might need to create symlinks for the gnu tools to be used. | |||
Example: | |||
<pre> | |||
ln -s /usr/bin/ggrep /usr/bin/grep | |||
</pre> | |||
You might also create bash aliases for gnu utils. | |||
$HOME/.bashrc aliases example: | |||
<pre> | |||
# alias to gnu ls instead of busybux | |||
alias ls='gls --color=auto' | |||
alias ll='ls -l' | |||
alias la='ls -la' | |||
alias md='mkdir' | |||
alias rd='rmdir' | |||
# aliases to gnu grep instead of busybux | |||
alias grep='ggrep' | |||
alias egrep='gegrep' | |||
alias fgrep='gfgrep' | |||
</pre> | </pre> | ||
