I totally dislike asking questions in forums but this one eats up to much of my time I need to spend on other topics.
I have a shell-script in which I call a terminal.
I want to invoke bash inside the terminal and print a message inside bash with aid of a here document.
See yourself.
works just fine and opens up a terminal with bash inside. But if I try to pass a command to bash itself the script fails.
I don't get it working.
A much nicer approach would be if I can pass a function (declared and defined) to bash?
I suppose the problem is, that bash is running in the context of the subshell of the terminal but my imagination and knowledge ends there.
I am almost sure that piping the result of a function in such a nested scenario is impossible.
"Is there any substituation of last command or script syntax which can be used as a user. As far I know the "last" command is being used to display information about previous logins. A member of adm group or the user adm can execute it only.
Thanks in advance for your usual help.

What is the actual difference between these two? Why the following code works for process substitution and fails for command substitution?

while IFS='\n' read -r... (3 Replies)

Hey, guys!
Trying to research this is such a pain since the read command itself is a common word. Try searching "unix OR linux read command examples" or using the command substitution keyword. :eek:
So, I wanted to use a command statement similar to the following.

Hi,
I almost always use back quotes in scripts to assigin output of a command to a variable.
eg: file=`basename a/b/c/d/file`

file=$(basename a/b/c/d/file)

gst-complete
gst-complete-0.8(1) User Commands gst-complete-0.8(1)NAME
gst-complete-0.8, gst-complete - perform bash completion for gst-launch command lines
SYNOPSIS
complete -Cgst-complete-0.8 gst-launch
gst-complete [--gst-list-mm] [--gst-mm=string] [--print]
DESCRIPTION
gst-complete-0.8 enables bash to provide context-sensitive tab completion for gst-launch command lines. See gst-launch(1) for the syntax of
gst-launch command lines.
You must have a version of bash that supports programmable completion. Such versions of bash provide the complete built-in command.
gst-complete is a wrapper script that runs the latest installed version of gst-complete-X.X. For example, if both gst-complete-0.7 and gst-
complete-0.8 are installed on your system, gst-complete runs gst-complete-0.8.
OPTIONS
The following options are supported by gst-complete-0.8 and gst-complete:
--help Display detailed usage message. You can also use -? to specify this option.
The following options are supported by gst-complete only:
--gst-list-mm List found major/minor versions. This option displays the versions that are available.
--gst-mm=string Force major/minor version. This option enables you to specify a specific version to run, if you do not want to run the
default version.
--print Print wrapped command line. This option displays the command that will be run, and then runs the command.
EXAMPLES
Example 1: Generating the Registry of Available Plugins by Running gst-compprep
Run the following command in your .bash_profile or other appropriate place:
example% complete -C gst-complete-0.8 gst-launch
Example 2: Running the Wrapper Script and Displaying the Command Name
example% gst-complete --print
/usr/bin/gst-complete-0.8
FILES
The following files are used by this application:
/usr/bin/gst-complete-0.Executable for bash completion for gst-launch
/usr/bin/gst-complete Wrapper script that runs the latest installed version of gst-complete-X.X
