io redirection - redirect all output in a bash script when using set -x -

-

i have bash script has set -x in it. possible redirect debug prints of script , output file? ideally this:

#!/bin/bash set -x (some magic command here...) > /tmp/mylog echo "test"

and the

+ echo test test

output in /tmp/mylog, not in stdout.

this i've googled , remember myself using time ago...

use exec redirect both standard output , standard error of commands in script:

#!/bin/bash logfile=$$.log exec > $logfile 2>&1

for more redirection magic check out advanced bash scripting guide - i/o redirection.

if want see output , debug on terminal in addition in log file, see redirect copy of stdout log file within bash script itself.

if want handle destination of set -x trace output independently of normal stdout , stderr, see bash storing output of set -x log file.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
