Shell programming in sh.

1) Every shell file gegins with #!/[path to shell]/[name of shell]! to use bash, for example you would begin your shell script with

Code:
#!/bin/sh

to use tcsh you could use

Code:
#!/bin/tcsh

2) When you declare variables just type the variable name followed by the = sign. For example to create a variable named NAME and set it to "ME" enter

Code:
NAME="ME"

3) When using a variable in an expression (like an if, and so forth) precede the variable name by $. For example, to ser a variable caled VAR2 to NAME enter:

Code:
VAR2=$NAME

4) You can use commands in shell scripts as you do the shell. The advantage of shell scripts is that you can use macros. For example to list all files and all directories in the current directory that begin with NAME enter

ls $NAME*

The following file gets all of the files returned by ls and stroes them in foo. after that, it takes the last file listed by ls and stores it in final value. Then it prints the value of finalvalue.

Code:
finalvalue=""

for foo in `ls`
do
  echo $foo
done

finalvalue=$foo

echo "$finalvalue"


I would list more, but I ran out of time. Hope this helps.

dh_installdebconf

DH_INSTALLDEBCONF(1)                                                 Debhelper                                                DH_INSTALLDEBCONF(1)

NAME

       dh_installdebconf - install files used by debconf in package build directories

SYNOPSIS

       dh_installdebconf [debhelperoptions] [-n] [--params]

DESCRIPTION

       dh_installdebconf is a debhelper program that is responsible for installing files used by debconf into package build directories.

       It also automatically generates the postrm commands needed to interface with debconf. The commands are added to the maintainer scripts by
       dh_installdeb. See dh_installdeb(1) for an explanation of how that works.

       Note that if you use debconf, your package probably needs to depend on it (it will be added to ${misc:Depends} by this program).

       Note that for your config script to be called by dpkg, your postinst needs to source debconf's confmodule. dh_installdebconf does not
       install this statement into the postinst automatically as it is too hard to do it right.

FILES

       debian/package.config
           This is the debconf config script, and is installed into the DEBIAN directory in the package build directory.

           Inside the script, the token #DEBHELPER# is replaced with shell script snippets generated by other debhelper commands.

       debian/package.templates
           This is the debconf templates file, and is installed into the DEBIAN directory in the package build directory.

       debian/po/
           If this directory is present, this program will automatically use po2debconf(1) to generate merged templates files that include the
           translations from there.

           For this to work, your package should build-depend on po-debconf.

OPTIONS

       -n, --no-scripts
           Do not modify postrm script.

       -- params
           Pass the params to po2debconf.

SEE ALSO

       debhelper(7)

       This program is a part of debhelper.
