Permission denied  In order to run a script the file must have an executable permission bit set   In order to fully understand Linux file permissions you can study the documentation for the chmod command  chmod  an abbreviation of change mode  is the command that is used to change the permission settings of a file   To read the chmod documentation for your local system   run man chmod or info chmod from the command line  Once read and understood you should be able to understand the output of running      ls -l foo sh       which will list the READ  WRITE and EXECUTE permissions for the file owner  the group owner and everyone else who is not the file owner or a member of the group to which the file belongs  that last permission group is sometimes referred to as  world  or  other    Here s a summary of how to troubleshoot the Permission Denied error in your case     ls -l foo sh                      Check file permissions of foo -rw-r--r-- 1 rkielty users 0 2012-10-21 14 47 foo sh                                                                 Owner  World                                   Name of    Group              Group              Name of                Owner    Owner has read and write access rw but the - indicates that the executable permission is missing  The chmod command fixes that   Group and other only have read permission set on the file  they cannot write to it or execute it      chmod  x foo sh                 The owner can set the executable permission on foo sh   ls -l foo sh                    Now we see an x after the rw  -rwxr-xr-x 1 rkielty users 0 2012-10-21 14 47 foo sh              foo sh is now executable as far as Linux is concerned   Using sudo results in Command not found  When you run a command using sudo you are effectively running it as the superuser or root    The reason that the root user is not finding your command is likely that the PATH environment variable for root does not include the directory where foo sh is located  Hence the command is not found    The PATH environment variable contains a list of directories which are searched for commands  Each user sets their own PATH variable according to their needs   To see what it is set to run   env   grep  PATH   Here s some sample output of running the above env command first as an ordinary user and then as the root user using sudo   rkielty rkielty-laptop    env   grep  PATH PATH  usr local sbin  usr local bin  usr sbin  usr bin  sbin  bin  usr games  rkielty rkielty-laptop    sudo env   grep  PATH  sudo  password for rkielty   PATH  usr local sbin  usr local bin  usr sbin  usr bin  sbin  bin  usr X11R6 bin   Note that  although similar  in this case the directories contained in the PATH the non-privileged user  rkielty  and the super user are not the same   The directory where foo sh resides is not present in the PATH variable of the root user  hence the command not found error

Check that you have execute permission on the script  i e  chmod  x foo sh Check that the first line of that script is    bin sh or some such  For sudo you are in the wrong directory  check with sudo pwd

Ok this is my solution  in    bash aliases just add the following     ADDS MY PATH WHEN SET AS ROOT if     id -u     0     then    export PATH  PATH  home your user bin  fi   Voila   Now you can execute your own scripts with sudo or set as ROOT without having to do an export PATH  PATH  home your user bin everytime   Notice that I need to be explicit when adding my PATH since HOME for superuser is  root

The other solutions I ve seen here so far are based on some system definitions  but it s in fact possible to have sudo use the current PATH  with the env command  and or the rest of the environment  with the -E option  just by invoking it right   sudo -E env  PATH  PATH   lt command gt   arguments    In fact  one can make an alias out of it   alias mysudo  sudo -E env  PATH  PATH      It s also possible to name the alias itself sudo  replacing the original sudo

It seems that linux will say  command not found  even if you explicitly give the path to the file    veeam jsandbox     sudo  tmp uid sh echo    sudo   tmp uid sh  command not found 1  veeam jsandbox     chmod  x  tmp uid sh  veeam jsandbox     sudo  tmp uid sh echo    0   It s a somewhat misleading error  however it s probably technically correct  A file is not a command until its executable  and so cannot be found

Try chmod u x foo sh instead of chmod  x foo sh if you have trouble with the guides above  This worked for me when the other solutions did not

You can also create a soft link to your script in one of the directories   usr local bin for example  in the super user PATH  It ll then be available to the sudo   chmod  x foo sh sudo ln -s path-to-foo sh  usr local bin foo   Have a look at this answer to have an idea of which directory to put soft link in

It seems sudo command not found to check whether the sudo package is installed on your system  type sudo   and press Enter   If you have sudo installed the system will display a short help message  otherwise you will see something like sudo  command not found To install sudo  run one of the following commands using root account  apt-get install sudo    If your system based on apt package manager yum install sudo        If your system based on yum package manager
