问题 I want to write a GUI/Terminal based application where I would need to clear the terminal and then write out the gui. But how do I reset the terminal back to normal once the application is finished? 回答1: Terminals (such as xterm and "any" which emulate it) support a feature called the alternate screen.

问题 I have a question over the script Googliser and the Mac commands. I tried the script some days ago in the Mac shell and made it work. I followed the script listed here: brew install wget brew install gnu-getopt brew link --force gnu-getopt curl -sO https://raw.githubusercontent.com/teracow/googliser/master/googliser.sh sed -i "" "s/readlink/stat/;s/dev\/shm/tmp/;s/p -p/p -t/" googliser.sh chmod +x googliser.sh Easy. It worked, not the first time, and I don't remember how I made it work. But

问题 I have a log file and I am trying to write a shell script to find multiple strings in a file on multiple lines. For example if I see the phrases "class=com.comcast.parker.GetCurrentAudioLanguageResponse" and "status:OK" together in the logs, I should print getAudioLanguage SUCCESSFUL else getAudioLanguage FAILED. So my shell script goes like this: Scriptfile: logfile=$1 if grep "{\"class\":\"com.comcast.parker.GetCurrentAudioLanguageResponse\"" jags.txt | grep "{\"status\":\"OK\"" | wc -l ;

Example: $ ls -l myfile -rw-r----- 1 me me 0 Aug 7 12:36 myfile $ cat myscript ls -l myfile $ bash myscript : No such file or directory The file clearly exist, but even if I didn't, this is the kind of error message I

问题 I'm trying to write a script to swap out text in a file: sed s/foo/bar/g myFile.txt > myFile.txt.updated mv myFile.txt.updated myFile.txt I evoke the sed program, which swaps out text in myFile.txt and redirects the changed lines of text to a second file. mv then moves .updated txt file to myFile.txt, overwriting it. That command works in the shell. I wrote: #!/bin/sh #First, I set up some descriptive variables for the arguments initialString="$1" shift desiredChange="$1" shift document="$1"
