How would I get my Vagrant shell script to supply the password when creating a user while provisioning phpPgAdmin?
ie. when I supply this command sudo htpasswd -c /etc/phppgadmin/.htpasswd vagrant it prompts for a password for the vagrant user so I can login to phpPgAdmin. How can I script this into my shell provisioning script that goes with my Vagrantfile?
First, you need to force htpasswd to read passwords from stdin. It can be done by supplying -i switch.
Second, you need to pass a string into htpasswd stdin. This can be achieved in numerous ways. For example you can redirect stdout of echo into stdin of htpasswd.
So resulting command would look like this
echo "123456" | htpasswd -i -c /etc/phppgadmin/.htpasswd vagrant
Using sqlite3 from bash on OS X seems fairly straightforward (I'm no expert at this, by the way). You will need to find out which table you need. You can do this with an interactive session.

The -v option to grep inverts the search, reporting only the lines that don't match the pattern. Since you know how to use grep to find the lines to be deleted, using grep -v and the same pattern will give you all the lines to be kept. You can write...
If you want to redirect the normal standard input of the program, you could use so called "here documents" (see e.g. the BASH manual page): java -jar script.jar <<EOF your input here EOF That means standard input (a.k.a. stdin) is redirected and will be the text in the "here document",...

The most common issue when handling variables containing paths of directories and files is the presence of special characters such as spaces. To handle those correctly, you should always quote the variables, using double quotes. Better code would therefor be: sudo sh "$path/join.sh" sudo sh "$path/join2.sh" It is also advised...
Executable files may be scripts (in which case you can read the text), or binaries (which are ELF formatted machine code). Your shell script is a script; git is an ELF binary. You can use the file command to see more detail. For example, on my nearest Linux system: $...

Checking file and/or directory existence To check whether a file exists in bash, you use the -f operator. For directories, use -d. Example usage: $ mkdir dir $ [ -d dir ] && echo exists! exists! $ rmdir dir $ [ -d dir ] && echo exists! $ touch file...

What I have tried sed 's/[a-z],[a-z]/[a-z], [a-z]/g' <<< "suny stony brook, stony brook,usa." You need to use regex's capture groups here to refer to the original [a-z] values.
