ls,sudo commands not found (shell commands)

Question

I tried to install laravel Framework in my mac OSX 10 .And I ended modifying my ~/.bash_profile to add the laravel command. laravel command seems to work normally .But another problem came out . ls ,sudo ...and other shell commands does not work .

-bash: ls: command not found

My bash.profile file contains the two links

export PATH="/Applications/MAMP/bin/php/php5.6/bin"
export PATH="$PATH:$HOME/.composer/vendor/bin"

Answer 1

The binaries for the above mentioned utilities for debian distribution are usually in /bin or /usr/bin directory. Of course exporting path won't help if the binaries are not there.

There could be one simple approach to it -

• Check for the location of binaries and then export the path in the bash_profile or .bashrc.

• Run the bashrc script (. ~/.bashrc) following you may not require a reboot.

Answer 2

check in ~/.bash_profile if this PATHs exist

export PATH=/opt/local/bin:/opt/local/sbin:$PATH

your complete line should looks like this

export PATH=/Applications/MAMP/bin/php/php5.6/bin:$HOME/.composer/vendor/bin:/opt/local/bin:/opt/local/sbin:$PATH

reboot needed.
