Top Forums Shell Programming and Scripting creating printf statement using user arguments Post 302627171 by kristinu on Friday 20th of April 2012 10:23:05 AM

Ahhh Yes.

In my situation I will be using "$@"

How can I modify this to exclude the last arguments, ot the last two arguments?

---------- Post updated at 08:53 AM ---------- Previous update was at 08:32 AM ----------

I have now coded the following:

Code:
length=$(($#-2))
 array="${@:1:$length}"
 echo "All Arguments except last two"
 printf "$frmt" "$array"
 

echo "All Arguments"
 printf "$frmt" "$@"


The problem is this:


"$@" allows the each parameter to become a single word, so that "$@" is equivalent to "$1" "$2", because some arguments will have contain embedded blanks.



However calling $array does not allow me to do things as "$@" does, even though the array manages to drop the last two arguments.

I managed to make it work using the following



Code:
printf "$frmt" "${@:1:$(($#-2))}"

WMANAGER(1)						    BSD General Commands Manual 					       WMANAGER(1)

NAME
wmanager -- choose a window manager and launch it SYNOPSIS
wmanager [OPTIONS ...] DESCRIPTION
The wmanager program displays a choice of the window managers listed in the ~/.wmanagerrc file. When one is picked, the related command is written to standard output, intended to be used by shell scripts. If the program is exited without choosing a window manager, ``-1'' is written to standard output. -fg COLOR Set the foreground color. -bg COLOR Set the background color. -bg2 COLOR Set the widget background color -di[splay] host:n.n Set the X display. -dn[d], -nod[nd] Enable/disable drag & drop, probably does nothing. -g[eometry] WxH+X+Y Set the window size and location. -i[conic] Start as iconified. -k[bd], -nok[bd] Enable/disable keyboard support. -na[me] CLASSNAME Set the X window class. -s[cheme] SCHEME Unknown, probably does nothing useful. -ti[tle] WINDOWTITLE Set the window title. -to[oltips], -not[ooltips] Enable/disable tooltips, probably does nothing. EXAMPLE
To start using wmanager, create a ~/.wmanagerrc file - generally with wmanagerrc-update(1) - and add something like the following at the end of your ~/.xsession file: WM="$(wmanager -geometry +570+585)" ... exec $WM See also wmanager-loop(1) for a nicer way to start wmanager. SEE ALSO
