Made some basic utilites for cross-plattform usage, as well as for unified and simplified usage.
Reused and wraped RudiC's echo_, thanks again
Code:
#
# Some tools
#
swarm.util.isRoot() { #
# Returns TRUE if user ID is 0
# Returns FALSE otherwise
if [[ ${UID:-${EUID:-0}} -eq 0 ]]
then $ECHO true
return 0
else $ECHO false
return 1
fi
}
swarm.util.isGUI() { #
# Returns TRUE if XDG_CURRENT_DESKTOP, DESKTOP_SESSION or XAUTHORITY is set
# Returns FALSE otherwise
if [[ -n "${XDG_CURRENT_DESKTOP:-${DESKTOP_SESSION:-$XAUTHORITY}}" ]]
then $ECHO true
return 0
else $ECHO false
return 1
fi
}
swarm.util.mkdir() { # /path/to/make
# Creates full path structures
#
${isRO:-false} && return 1
# Remove any possible args from ARGS
while [[ "-" == "${1:0:1}" ]] ; do shift ; done
swarm.protect "$FUNCNAME" "${@}" && return 1
# Vars
local dir_done=""
local dir_todo=$($PRINTF "${1:1}" | $SED s,"/","\n",g)
# Start pipe
$PRINTF '%s\n' "$dir_todo" | while read current
do # Prepare next dir
dir_done+="/$current"
# Create if not exist
[[ -d "$dir_done" ]] || $MKDIR "$dir_done"
done
return 0
}
swarm.util.echo() { # [-e|-n|-en|-ne] STRING
# Simple echo's, by RudiC @ unix.com
#
echo_(){
( IFS=" "; $PRINTF "%s\n" "$*" )
}
# Portable echo -n
echo_n() {
( IFS=" "; $PRINTF "%s" "$*" )
}
# Portable echo -e
echo_e() {
( IFS=" "; $PRINTF "%b\n" "$*" )
}
# Portable echo -ne
echo_ne() {
( IFS=" "; $PRINTF "%b" "$*" )
}
case "${1/-}" in
"n") shift ; echo_n "${@}" ;;
"e") shift ; echo_e "${@}" ;;
"en"|"ne")
shift ; echo_ne "${@}" ;;
*) echo_ "${@}" ;;
esac
}
swarm.util.isDir() { # /path/to/dir
# Returns true if passed string is a directory
#
[[ -d "$1" ]]
return $?
}
#
# Short variable access to util functions
# and to keep file usage to a minimum

But currently I'm still busy in re-thinking/doing the init procedure....
Well, unifying (is that a word??) the procedure of using functions to do different checks, keep/put all variables to RAM while put some essential ones (usage speed increase / customize options) in the 'rc' file.
The specific part of preparing configuration files & folders that are optional - because it must run on a Read-Only system as well, is quite more challenging than making it just in a "must-be-installed" way.
Also, with my... crazy... idea of implementing an optional ramdisk support (as root, for configuration and tempfiles only) didnt make the init procedure any easier.
Further, I need to 'bypass' the (so far hardcoded) use of /root because not all systems have it, thus I have to place the configfile (swarmrc) in another place, like using '/etc' if root has no $HOME.
this is the output i am getting here..

Hi,
I am trying to capture runtime stats of a shell script (c shell). Are there system variables to call? Or should I create a date variable at the start of the script and at the end of the script? I am trying to capture the time if the script stops or ends with error.
Please help.

__________________________________________________________________________________________________________________________________________________NAME
page_util_quote - page character quoting utilities
SYNOPSIS
package require page::util::quote ?0.1?
package require snit
::page::util::quote::unquote char
::page::util::quote::quote'tcl char
::page::util::quote::quote'tclstr char
::page::util::quote::quote'tclcom char
_________________________________________________________________DESCRIPTION
This package provides a few utility commands to convert characters into various forms.
API
::page::util::quote::unquote char
A character, as stored in an abstract syntax tree by a PEG processor (See the packages grammar::peg::interpreter, grammar::me, and
their relations), i.e. in some quoted form, is converted into the equivalent Tcl character. The character is returned as the result
of the command.
::page::util::quote::quote'tcl char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser, will
regenerate the character in question and is 7bit ASCII. The string is returned as the result of this command.
::page::util::quote::quote'tclstr char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser and
will generate a human readable representation of the character in question. The string is returned as the result of this command.
The string does not use any unprintable characters. It may use backslash-quoting. High UTF characters are quoted to avoid problems
with the still prevalent ascii terminals. It is assumed that the string will be used in a double-quoted environment.
::page::util::quote::quote'tclcom char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser when
used within a Tcl comment. The string is returned as the result of this command.
