O comando está disponível em…; O comando não pôde ser localizado

Question

Eu tenho um problema no meu terminal. Acabei de baixar um emulador do Android e isso acontece no meu terminal. Eu tenho usado o Ubuntu 12.04.

Command 'lesspipe' is available in the following places
 * /bin/lesspipe
 * /usr/bin/lesspipe
The command could not be located because '/usr/bin:/bin' is not included in the PATH environment variable.
lesspipe: command not found
Command 'dircolors' is available in '/usr/bin/dircolors'
The command could not be located because '/usr/bin' is not included in the PATH environment variable.
dircolors: command not found
Command 'uname' is available in '/bin/uname'
The command could not be located because '/bin' is not included in the PATH environment variable.
uname: command not found
bash: [: =: unary operator expected
Command 'sed' is available in '/bin/sed'
The command could not be located because '/bin' is not included in the PATH environment variable.
sed: command not found
Command 'ls' is available in '/bin/ls'
The command could not be located because '/bin' is not included in the PATH environment variable.
ls: command not found

    

Answer 1

Execute o seguinte:

export PATH=/bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin:/usr/local/sbin:/home/sweet/android-sdk-linux/platfrom-tools

Agora tente executar os comandos.

se você quiser salvá-lo permanentemente para não precisar digitá-lo repetidamente, abra ~/.bashrc usando gedit por /usr/bin/gedit ~/.bashrc e encontre a linha {PATH}:/home/sweet/android-sdk-linux/platfrom-tools . Em seguida, exclua essa linha ou coloque um # na frente para comentá-la. Em seguida, adicione a seguinte linha:

export PATH=/bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin:/usr/local/sbin:/home/sweet/android-sdk-linux/platfrom-tools

agora salve o arquivo e, a partir do terminal, execute source ~/.bashrc para que seu caminho seja configurado corretamente a partir da sessão de terminal atual.
