问题 I'm trying to transform txt file encoding from UTF8 to ANSI (cp1252). I need this because the file is used in a fixed position Oracle import (external Table) which apparently only supports CP1252. If I import an UTF-8 file, some special characters turn up as two incorrect characters instead. I'm working in a Unix machine (my OS is HP UX). I have been looking for an answer on the web but I don't find any way to do this conversion. For exmple, the POSIX iconv command doesn't have this choose,

问题 UPDATE: Based on below discussion I have edited my answer for more accurate description. I am trying to run a nohup command from jenkins. The full command is nohup java -jar /home/.../jar/server-process-0.35.jar prod >> /var/../server-process-prod.log 2>&1 & This command does not work.

问题 I'm using mac/linux and I know that ctrl-z stops the currently running command in terminal, but I frequently see the process is still running when i check the system monitor. What is the right way to stop a command in terminal? Typically I run into this issue when running python or ruby apps, i'm not sure if that has something to do with it, just thought I would add that. 回答1: Using control-z suspends the process (see the output from stty -a which lists the key stroke under susp ). That

问题 I've been using GDB for 1 day and I've accumulated a decent understanding of it. However when I set a breakpoint at the final semicolon using GDB and print registers I can't fully interpret the meaning of the data stored into the XMM register. I don't know if the data is in (MSB > LSB) format or vice versa. __m128i S = _mm_load_si128((__m128i*)Array16Bytes); } So this is the result that I'm getting. (gdb) print $xmm0 $1 = { v4_float = {1.2593182e-07, -4.1251766e-18, -5.43431603e-31, -2

问题 Apologies if I've formatted this terribly as I've not posted here before. I'm attempting to edit a file to remove double quotation marks that are wrapped around multiple strings of varied lengths. Some of these strings include capitalisation and white-space, normally I would just use a global search and replace, however, some of the strings CAN'T have the double quotes removed as they're required. An extract of the file in question is here: "tplan"."external_plan_ref" "Plan ID", 'CMP' CMP,
