nohup cannot find file or directory when running script to start davmail

I am trying to set up davmail on text based Ubuntu to run in server mode and am following the instructions here, but when I try to run the line

nohup davmail.sh davmail.properties & 

I get the message

nohup: failed to run command 'davmail.sh': No such file or directory 

The davmail.sh script is as follows:

#!/bin/sh # Ubuntu setup instructions : # install java : # sudo apt-get install default-jre # launch davmail BASE=`dirname $0` for i in $BASE/lib/*; do export CLASSPATH=$CLASSPATH:$i; done exec java -Xmx512M -Dsun.net.inetaddr.ttl=60 -cp $BASE/davmail.jar:$CLASSPATH davmail.DavGateway $1 

I don't know which file(s) it is referring to when it says No such file or directory. It seems to me that everything should be there. I am wondering if I am missing some package or something, or if the script really is just trying to reference some file that isn't there. I am pretty new to Linux, so any help here would be greatly appreciated! Here is the tree of the directory the script resides in:

I can see from your tree listing that you are “in” the top-level directory of that tree (i.e., it is your current directory)¹, and that davmail.sh is also in that top-level directory.  Do you have . (dot; i.e., the current directory) in your search path?  If you do, take it out, and keep on looking for an answer.

But if you don’t have . (dot; i.e., the current directory) in your search path (i.e., if you have a proper configuration), then you will need to do one of the following:

• Type nohup ./davmail.sh davmail.properties &
• Type nohup /full/path/to/current/directory/davmail.sh davmail.properties &, or
• Put the current directory name (i.e., the name of the directory where davmail.sh is) into your search path,

… so nohup will know where to find davmail.sh.

I ran into the same problem. In my case, nohup was calling a script that was created in a windows machine. The script's line endings was CR LF instead of LF.

Running the script directly evidenced the error (example).

I just changed from Windows End-of-lines (CR LF) to Unix End-of-lines (LF) and it worked. Any decent text editor or IDE can do that for you.
