I was playing with the installation of Mongo db on my mac... and in exporting the Mongodb/bin dir to PATH .. looks like I corrupted the bash_profile and now I can't find it..
This is what I did :
nano ~/.bash_profile
The file did not exist, so I went ahead created one and added the following line
export PATH={$PATH}:~/mongo/bin
So now I saved the file .. by pressing ctrl + O and then hit Enter at the prompt. Then I pressed ctrl + X to exit nano. I reloaded my bash profile with the following command:
$ source ~/.bash_profile.
.....
Now even the basic commands like open, clear , grep etc would result in
-bash: clear: command not found
When I do
export $PATH
this is what shows up ...
*
-bash: export: `{{/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin}:/Users/pavbond007/Documents/Mongo/mongodb-osx-x86_64-2.2.3/bin}:/Users/pavbond007/Documents/Mongo/mongodb-osx-x86_64-2.2.3/bin': not a valid identifier

I am a novice in this.. Please help me get back to my original state where I had access to all the mac and unix commands..
Let me know if you require additional details.. My OS is mountain lion.. I had also XCode installed..
I suspect the issue is that $PATH is being expanded when you don't want it to be. The export command isn't treated any differently. Export expects the name of an environment variable to export, but you aren't giving it the name of the variable, you are giving it the variable reference itself, which gets expanded.
Think about this:
echo PATH
outputs
PATH
However, this
echo $PATH
outputs this:
{{/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin}:/Users/pavbond007/Documents/Mongo/mongodb-osx-x86_64-2.2.3/bin}:/Users/pavbond007/Documents/Mongo/mongodb-osx-x86_64-2.2.3/bin
Therefore, to export the PATH variable, try this instead (notice the lack of dollar sign):
export PATH
Also, I noticed your $PATH has a bunch of curly braces in it. Take those out. I'm pretty sure that is breaking things.
To do this in one line like you tried first, let's bring it all together:
export PATH=$PATH:~/mongo/bin
