If there's a file called example.txt with contents:
Foo
Bar
Baz
Goo
then I need to generate a shell script that has commands to reconstruct example.txt on another machine:
I use for i in * to search a directory and conduct the above operation on every file that's not binary. Suppose i points to example.txt now, as the above example shows. I used sed to extract the contents of the files line by line. The question is how to use the result extracted by sed as the argument of echo?
I tried:
Here tmp is the content of each line, but $tmp didn't evaluate in echo.
Actually the purpose of doing so is to transfer a directory containing various files and subdirectories which also contain files to another machine through simple email. Only bundle.sh needs to be transferred. So when the shell script bundle.sh is run on the other machine, the whole directory will be constructed there. I'm writing a script that can generate the bundle.sh script. And of course this needs to be done recursively since there're subdirectories, but ignore it for now. Thanks.

Hi,
I basically have 2 shell scripts.
One is a shell script will get the variable value from the user. The variable is nothing but the IP of the remote system.
Another shell script is a script that does the job of connecting to the remote system using ssh. This uses a expect utility in turn.

apt-config
APT-CONFIG(8) APT APT-CONFIG(8)NAME
apt-config - APT Configuration Query program
SYNOPSIS
apt-config [-hv] [-o=config string] [-c=file] {[shell] | [dump]}
DESCRIPTION
apt-config is an internal program used by various portions of the APT suite to provide consistent configurability. It accesses the main
configuration file /etc/apt/apt.conf in a manner that is easy to use by scripted applications.
Unless the -h, or --help option is given one of the commands below must be present.
shell
shell is used to access the configuration information from a shell script. It is given pairs of arguments, the first being a shell
variable and the second the configuration value to query. As output it lists a series of shell assignments commands for each present
value. In a shell script it should be used like:
OPTS="-f"
RES=`apt-config shell OPTS MyApp::options`
eval $RES
This will set the shell environment variable $OPTS to the value of MyApp::options with a default of -f.
The configuration item may be postfixed with a /[fdbi]. f returns file names, d returns directories, b returns true or false and i
returns an integer. Each of the returns is normalized and verified internally.
dump
Just show the contents of the configuration space.
OPTIONS
All command line options may be set using the configuration file, the descriptions indicate the configuration option to set. For boolean
options you can override the config file by using something like -f-,--no-f, -f=no or several other variations.
-h, --help
Show a short usage summary.
-v, --version
Show the program version.
-c, --config-file
Configuration File; Specify a configuration file to use. The program will read the default configuration file and then this
configuration file. If configuration settings need to be set before the default configuration files are parsed specify a file with the
APT_CONFIG environment variable. See apt.conf(5) for syntax information.
-o, --option
Set a Configuration Option; This will set an arbitrary configuration option. The syntax is -o Foo::Bar=bar. -o and --option can be
used multiple times to set different options.
SEE ALSO apt.conf(5)DIAGNOSTICS
apt-config returns zero on normal operation, decimal 100 on error.
