Hello everyone,
I am struggling a bit with a batch script that I need to run in cygwin. I work in winXP and I had to write some awk scripts to do some file manipulation, and now I would like to automate the process by just running a batch file so that my colleagues can use it easily.
Now, the... (2 Replies)
I'd like to streamline the code more than a bit to get it to run faster.
There's a thread about this and related issues of mine on the Cygwin mailing-list, but I want to eliminate any chances it might just be inefficient/inelegant/crappy code. A previous run of the same script on both Cygwin and... (6 Replies)
Hmmm.... I love these forums because I always get great prompt responses and I want to ask a question about running bash on windows. Is that allowed?
Now I know I can install cygwin cron and run bash that way.
Can I run bash from windows schedule task? How?
thanks

As stated, I am looking into keeping my backup drive unmounted in normal windows use. Partly this is to address threats like cryptolocker. Since one of my backup drives is an internal drive, it will not likely afford any protection from such a threat. I am thinking of adding code to my rsync script... (5 Replies)

I am trying to use a batch file to automatically execute a bash script with no luck this far.
The batch script looks like this:
C:\Cygwin64\bin\bash test.sh
I have also tried this:
C:\Cygwin64\bin\bash "C:\Cygwin64\bin\test.sh"
Needless to say that the windows box has Cygwin... (7 Replies)

catch
catch(1T) Tcl Built-In Commands catch(1T)__________________________________________________________________________________________________________________________________________________NAME
catch - Evaluate script and trap exceptional returns
SYNOPSIS
catch script ?varName?
_________________________________________________________________DESCRIPTION
The catch command may be used to prevent errors from aborting command interpretation. The catch command calls the Tcl interpreter recur-
sively to execute script, and always returns without raising an error, regardless of any errors that might occur while executing script.
If script raises an error, catch will return a non-zero integer value corresponding to the exceptional return code returned by evaluation
of script. Tcl defines the normal return code from script evaluation to be zero(0), or TCL_OK. Tcl also defines four exceptional return
codes: 1 (TCL_ERROR), 2 (TCL_RETURN), 3 (TCL_BREAK), and 4 (TCL_CONTINUE). Errors during evaluation of a script are indicated by a return
code of TCL_ERROR. The other exceptional return codes are returned by the return, break, and continue commands and in other special situa-
tions as documented. Tcl packages can define new commands that return other integer values as return codes as well, and scripts that make
use of the return -code command can also have return codes other than the five defined by Tcl.
If the varName argument is given, then the variable it names is set to the result of the script evaluation. When the return code from the
script is 1 (TCL_ERROR), the value stored in varName is an error message. When the return code from the script is 0 (TCL_OK), the value
stored in resultVarName is the value returned from script.
If script does not raise an error, catch will return 0 (TCL_OK) and set the variable to the value returned from script.
Note that catch catches all exceptions, including those generated by break and continue as well as errors. The only errors that are not
caught are syntax errors found when the script is compiled. This is because the catch command only catches errors during runtime. When
the catch statement is compiled, the script is compiled as well and any syntax errors will generate a Tcl error.
EXAMPLES
The catch command may be used in an if to branch based on the success of a script.
if { [catch {open $someFile w} fid] } {
puts stderr "Could not open $someFile for writing
$fid"
exit 1
}
The catch command will not catch compiled syntax errors. The first time proc foo is called, the body will be compiled and a Tcl error will
be generated.
proc foo {} {
catch {expr {1 +- }}
}
