I guess as they say, RTFM more carefully. Just kidding.
NAME=${0##*/}
simply gets the name of the currently executing script. The $0 is what does it, and the rest strips of the leading path names. It's useful when the script name is supposed to different things depending on how its invoked. For instance, if you have a softlink to your script named "foo" and another softlink named "bar", then your script can do print out "FU" instead of "Beyond All Recognition". Or something.
set -xv +xv are shorthand for
Code:
set -x
set -v
The first turns on "eXecution debugging". Every command that is executed, and after parsing, is printed to stderr. The second turns on "Verbose mode" which prints to stderr every line that is read in and before being parsed, whether or not it is executed.
Found this piece of code written in ksh. I have no ideas what do the stuff like ${SRF##*\.} do.
SUFFIX=${SRF##*\.}
if ; then
SUFFIX=""

I have encountered similar expressions in other programs also. Any pointers on where to learn more about these... (1 Reply)

source
source(n) Tcl Built-In Commands source(n)
__________________________________________________________________________________________________________________________________________________NAME
source - Evaluate a file or resource as a Tcl script
SYNOPSIS
source fileName
source -encoding encodingName fileName |
_________________________________________________________________DESCRIPTION
This command takes the contents of the specified file or resource and passes it to the Tcl interpreter as a text script. The return value
from source is the return value of the last command executed in the script. If an error occurs in evaluating the contents of the script
then the source command will return that error. If a return command is invoked from within the script then the remainder of the file will
be skipped and the source command will return normally with the result from the return command.
The end-of-file character for files is "32" (^Z) for all platforms. The source command will read files up to this character. This
restriction does not exist for the read or gets commands, allowing for files containing code and data segments (scripted documents). If
you require a "^Z" in code for string comparison, you can use " 32" or "u001a", which will be safely substituted by the Tcl interpreter
into "^Z".
The -encoding option is used to specify the encoding of the data stored in fileName. When the -encoding option is omitted, the system |
encoding is assumed.
EXAMPLE
Run the script in the file foo.tcl and then the script in the file bar.tcl:
source foo.tcl
source bar.tcl
Alternatively:
foreach scriptFile {foo.tcl bar.tcl} {
source $scriptFile
}
