How to escape special characters in PowerShell?

由 可紊 提交于 2019-12-01 12:49:57
When my PowerShell script runs, it prompts the user for a password parameter. That password can contain any number of special characters like *\~;(%?.:@/ That password is then used as a parameter for a .exe command, but it is often incorrect due to some special characters not being escaped properly. An example past password was $(?-.?-(. The only characters I needed to escape was '(', which I replaced with '`(' to make it work. However, that password is now expired. The new password is something like *\~;~(%?.:@/ *NOTE: these passwords have random numbers and letters mixed into them as well,

Batch file: Escape questionmark in for loop

由 五迷三道 提交于 2019-12-01 11:32:31
This for loop (reduced minimal example); @echo off for %%a in (help -help --help /help ? /?) do ( echo %%a ) chokes on the 2 elements with a '?' character. It outputs C:\Temp>test.bat help -help --help /help C:\Temp> So it just quits the loop when it hits the first '?'. What is the proper escape sequence for this set? Tried a bunch of stuff, double quotes, carets, backslash, etc. but nothing seems to work. Another option is to use linefeeds within a FOR /F string. FOR /F will treat each line as an independent string. Below I show four ways to do the same thing. @echo off setlocal

How to escape a NULL byte as an argument to a shell command inside a Makefile

由 房东的猫 提交于 2019-12-01 11:20:10
Inside a Makefile I run a shell command which I want to pass a NULL byte as argument. The following attempt fails: echo $(shell /bin/echo -n $$'\x00' | ruby -e "puts STDIN.read.inspect") It generates: echo "$\\x00" Instead I expected: echo "\u0000" How do I properly escape such a NULL byte? echo disables interpretation of backslash escapes by default. You need to supply the -e option to enable it. $ echo -ne "\x00" | ruby -e "puts STDIN.read.inspect" "\u0000" Due to the execve(2) semantics it is not possible to pass a string containing a null byte as argument. Each argument string is

Printing string in Perl

由 岁酱吖の 提交于 2019-12-01 11:09:55
Is there an easy way, using a subroutine maybe, to print a string in Perl without escaping every special character? This is what I want to do: print DELIMITER <I don't care what is here> DELIMITER So obviously it will great if I can put a string as a delimiter instead of special characters. perldoc perlop , under "Quote and Quote-like Operators", contains everything you need. While we usually think of quotes as literal values, in Perl they function as operators, providing various kinds of interpolating and pattern matching capabilities. Perl provides customary quote characters for these

How to go to the previous line in a C code

由 狂风中的少年 提交于 2019-12-01 11:00:59
If for the following code: printf("HEllo\n"); // do not change this line. printf("\b\bworld"); I need an output: Helloworld (In a single line). But this does not work fine. Could anyone please explain the reason? And other escape sequence if any. Remove "\n" from your first printf. It moves the cursor to a new line. Here is the list of escape sequences. If you can't remove "\n", then you can do make a copy of a substring without these charaters. See the following example: const char* from = "12345678"; char *to = (char*) malloc(6); strncpy(to, from+2, 5); All you need is to determine the index

Fix JSLint bad escapement warning in RegEx

由 元气小坏坏 提交于 2019-12-01 10:00:25
问题 I have the following code in a 3rd party jQuery control called jquery.facebox.js that JSLint doesn't like. It's a bad escapement error in a RegEx. Regular expression are like Romulan to me, so I can't see how to fix the error (which is with the period character in the RegEx): var imageTypes = $.facebox.settings.imageTypes.join('|'); $.facebox.settings.imageTypesRegexp = new RegExp('\.(' + imageTypes + ')$', 'i'); 回答1: Add a second \ after '\ . This is a string problem, not a regex problem :-)

Unmarshalling XML with JAXB without unescaping characters

由 雨燕双飞 提交于 2019-12-01 09:41:22
imagine following situation: we receive a xml file from some external tool. Lately within this xml, there can be some escaped charakters in nodenames or within their richcontent tag, like in the following example (simplyfied): <map> <node TEXT="Project"> <node TEXT="ää"> <richcontent TYPE="NOTE"><html> <head> </head> <body> <p> I am a Note for Node ää! </p> </body> </html> </richcontent> </node> </node> </map> After unmarshalling the file with JAXB those escaped charakters get unescaped. Unfortunatly I need them to stay the way they are, meaning escaped. Is there any way to avoid unescaping

Unescaping characters in a string with Ruby

由 孤者浪人 提交于 2019-12-01 09:13:20
Given a string in the following format (the Posterous API returns posts in this format): s="\\u003Cp\\u003E" How can I convert it to the actual ascii characters such that s="<p>" ? On OSX, I successfully used Iconv.iconv('ascii', 'java', s) but once deployed to Heroku, I receive an Iconv::IllegalSequence exception. I'm guessing that the system Heroku deploys to does't support the java encoder. I am using HTTParty to make a request to the Posterous API. If I use curl to make the same request then I do not get the double slashes. From HTTParty github page: Automatic parsing of JSON and XML into
