show escape sequences in terminal?












-1















Is there a way to let the terminal show the raw escape sequence? (e.g. those used to control color)



I came across this UNIX.SE question, and want to filter "red" output ( Filter output of command by color)



However, the commands in the answers do not work for my output (e.g. the red in git status for "Untracked files"). They do work for the examples there echo -e '33[00;31mtest33[00m' | grep --color=none '[[:cntrl:]]'. Filtering with grep --color=none '[[:cntrl:]]' works on my output but also shows text with other colors.



I guess the red I see must be a different red than e[31m.



Is there a way to let terminal output raw escape sequences? (so that I can use the right sequence to filter the specific red color I see)



(bash, Ubuntu 18.04)

          You haven't made git think that it is writing to a terminal, so it isn't producing colour.

          How to rewrite equation of hyperbola in standard form

          Image
          2 $begingroup$ I was wondering about this question: $$ 9 x ^ 2 -4y^2-72x=0 $$ What is the step-by-step process of writing such an equation which, in this case, has the graph of a hyperbola in standard form? Please excuse me for my messy equation. As I am relatively new to Mathematics Stack Exchange, I do not know how to insert superscripts. Thank you ahead of time! calculus conic-sections share | cite | improve this question edited 2 hours ago Key Flex 8,637 6 12 33 asked 2 hours ago

          No ethernet ip address in my vocore2

          Image
          0 I just flashed my vocore2u with openwrt 18.06.1, and plug it with an ethernet cable to access network while setting up wireless access-point for my phone. The AP is working and connected to the network, but the ip in my phone is in the subnet of another router. And there's no ip assigned to my vocore2 so I cannot ssh into it. After connecting to vocore2 with serial terminal, ping 8.8.8.8 is also failed. How can I make my vocore2 gain ip from the router and setting up the network well? root@OpenWrt:/etc/config# ifconfig apcli0 Link encap:Ethernet HWaddr BA:D8:12:07:01:71 inet6 addr: fe80::b8d8:12ff:fe07:171/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 erro
