command

问题 I need a one line command for the below requirement. Search all the files from the root directory and print only those files names whose file name length is less than 25.

I am not sure about furthur command. 回答1: My GNU find supports this, unsure whether it's a part of standard find. find / -type f -regextype posix-extended -regex '.*/.{1,24}$' Alternatively, use find | grep. find / -type f |

问题 I'm trying to make a batch file that will compare two folders "core" and "custom" and return the names of the files that aren't in custom. So far I have this code, most of which is taken form another question on stack overflow. It creates "Arrays" of the files in each folder.

问题 I see the benefit of asynchronous commands (waiting for server responses...) but in my flex app it creates me more problem than anything. Here's what I want: EVERY command executes only after the previous one returned (to result or fault function) And I'd like to do this as easily as possible.. by the way the GUI must become irresponsive (maybe a wait message) while a long command is being executed (I could show the wait message in the execute function and remove it in the fault or result

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . What does "auwwx" mean in the command "ps auwwx"? According to the "man ps" ps - report process status ps gives a snapshot of the current processes.

问题 I know the title doesn't make sense, but I have one question. I have made this file called Test.bin and here's whats inside the .bin file: echo Hello World Since its a test file, I've been trying to see if i can make a batch file that can read the commands in the .bin file and output it onto the console. 回答1: Not sure what you are trying to do exactly, but I think you have two options: Rename test.bin as test.bat and run it with: test Start a new command interpreter and send it your commands:

Actually I am not sure which component I need to customize with Codename One Designer ? 回答1: In the theme constants tab you can set the dlgButtonCommandUIID variable to the UIID you want the buttons to take.

问题 I use Tortoise svn along with about 20 others at our site and all have an ongoing issue with it. Whenever you choose any command (update, commit, or ANY item of the right-click menu) there is almost always an initial lack of repsonse from the software.
