sudo - command not found

Hi,
I'm trying to install a patch onto a program but when I open the patch.command file, the patch tries to run but comes up with error messages:
"> Applying patches...
/Users/Chris/Desktop/Patch.command: line 14: sudo: command not found
/Users/Chris/Desktop/Patch.command: line 16: sudo: command not found
/Users/Chris/Desktop/Patch.command: line 18: sudo: command not found
/Users/Chris/Desktop/Patch.command: line 20: sudo: command not found"

When i open a terminal window and type in "sudo" it comes back with "-bash: sudo: command not found". Same thing for "which sudo" except the command "which" is not found. I'm a complete beginner and know nothing about programming so sorry if i've said anything wrong or this is the wrong area of the forum. ?
Thanks

What program are you trying to patch ?
What OS and version of the OS are you running ?

I'm trying to patch ableton live. I'm on OS X Yosemite v10.10.5

What version of Ableton Live and where did you get the update from ?

Cheers ... McBie

I believe it's version 9.1.9 , but I don't think it's to do with the update as when I enter "which sudo" or "sudo" these commands aren't found. When I was rooting my android phone I also had problems with Terminal when i tried to add commands to my $PATH. Is there any way i can fix the "sudo" command so that the patch will work properly?

Open Terminal and type "echo $PATH" without the quotes. Make sure /usr/bin is in there.

I, like cradom, suspect that this is simply a case of an incorrect PATH variable set. What did you change previously?

When i input echo $PATH all it returns is $ ... Obviously there's something wrong here. Would you be able to help me fix this? I haven't changed anything previously

Do you have a file called .bash_profile or .bashrc in your home directory (given that it starts with a ., it will be hidden). What do you see if you execute the following? If you don't have a .bash_profile, a simple solution to this issue is to create a file called .bash_profile in your home directory with the following contents: Restart Terminal and you should be good to go.

This is what comes up if i execute that:
. Applications
.. Desktop
.CFUserTextEncoding Documents
.DS_Store Downloads
.MakeMKV Knight and Day (Extended Edition)
.Motorola Mobility Library
.Trash Movies
.android Music
.bash_history Pictures
.bash_profile Public
.config cminstaller
.cups jagex_cl_runescape_LIVE.dat
.dropbox jagexcache
.jagex_cache_32 random.dat
.local

Sorry about the formatting but .bash_profile is in there.

If i input export $PATH this comes up:
-bash: export: `/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin': not a valid identifier

Not sure what this means?

I just tried to use sudo and it works! Thank you so much

Edit: I closed the terminal window and sudo no longer works. Is there a more permanent solution?

Open Terminal and do that command again:
PATH="/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin"
export PATH

Copy it from Van's post Now, without closing Terminal type:
nano .bash_profile
A "window" will open up. This is the nano editor.
Paste the command into the window (this is assuming it's not already there).
Now do a control-x. It will ask if you want to save, yes.
Restart Terminal. It should work now.

Awesome, thank you both !

I'm going to take my anti-hive meds now and whimper in the corner. ;D

Just pet the bunny. Takes care of everything...

One day Sly, one day we'll get you to embrace the command line.

Heh, good luck with that.
