In zsh’s read command, –p means –– guess –– “Input is read from the coprocess.” I suggest that you display your prompt with echo or printf . You may also need to replace –n 1 with –k or –k 1 .

Sep 5, 2021 · In zsh, you use -k to specify the number of characters to read, but it also defaults to reading from the terminal rather than stdin, so you have to also add -u 0 to tell it to read from stdin. Long story short: in zsh, use read -n '' -k 1 -u 0 somevar to …

Oct 22, 2021 · 起因是我在脚本里写的两个命令同时都用了 read ，区别在于一个是封装在 bash 脚本里的，另一个是封装成 zsh 函数。 因而当我使用 -p 参数的时候， zsh 就会报错给我 read: -p: no coprocess 。 当我反复确认没有拼写上的问题，我就确信这应该又是 zsh 和 bash 有区别的锅。 区别. 在 zsh 中， -p 意味着从一个协程读取输入，而 bash 则意味着一个提示，因此 zsh 会报 no coprocess 的错误。 假设我们的 bash 语句为. 则 zsh 得改成. 然后问题似乎是解决了。 更舒服 …

Jan 23, 2017 · In zsh's read, the closest option seems to be -k: Read only one (or num) characters. All are assigned to the first name, without word splitting.

May 23, 2012 · To input a line of text comfortably under zsh, use vared. Using vared instead of read invokes zle, which is the equivalent of passing -e in bash to invoke readline. The behavior you describe with plain read looks like a misconfigured terminal rather than a shell issue.

Apr 7, 2016 · In order to read in an array in zsh, read requires the option -A (instead of -a): Note: There are many more differences between zsh and bash: In zsh arrays are numbered from one by default, in bash they start from zero. To print the third element of …

Oct 21, 2018 · I'm trying to pipe a command's output to the read builtin of my shell and I get a different behaviour for zsh and bash: $ bash -c 'echo hello | read test; echo $test' $ zsh -c 'echo hello | read ...

May 14, 2022 · For those who do not have the necessary tools to process texinfo, precompiled documentation (PostScript, dvi, PDF, info and HTML formats) is available from the zsh archive site or its mirrors, in the file zsh-doc.tar.gz.

Jun 3, 2020 · I recently started to use zsh instead of bash and now i'm getting some problems that cannot be found on bash. One of theme: when i use read -p command, obviously with flag -p, i get an error that says: read: -p: no coprocess. On the other hand when I switch to bash again, this command works perfectly. My full command: read -p "what's your name ...
