在UNIX / usr / bin / script内继承别名 [英] Inheriting aliases inside UNIX /usr/bin/script

问题描述

然而，UNIX/ usr / bin / script命令将创建一个运行的shell会话的脚本（请参阅man脚本了解更多信息） ，当一个脚本实例，似乎忘记了父shell的env vars，别名等。

以下示例演示了 ll别名我定义在脚本内被忽略：

  zsh> mkdir temp 
 zsh> cd temp 
 
 zsh>别名ll = ls -alF
 
 zsh> ll 
 total 24 
 drwxr-xr-x 2 me mygroup 4096 Feb 18 13:32 ./ 
 drwxr-xr-x 28 me mygroup 8192 Feb 18 13:32 ../ 
 
 zsh>脚本a.out 
脚本启动，文件是a.out 
  

$ ll

  zsh：command not found：ll 
  

  $ exit 
脚本完成，文件是a.out 
 
 zsh> ll 
 total 32 
 drwxr-xr-x 2 me mygroup 4096 Feb 18 13:32 ./ 
 drwxr-xr-x 28 me mygroup 8192 Feb 18 13:32 ../ 
 -rw-r  -  r-- 1 me mygroup 182 Feb 18 13:32 a.out 
  

所以，如何让脚本进程从父shell继承env设置？

好的，env vars是没有忘记。只是别名重新采购.profile或某些工作...但是如何才能使自动发生？

解决方案

当我在bash下启动它时，它可以正常工作。也许在您的zsh配置中有一些东西被弄脏了，或者它不是源自你的zsh的启动文件。您可以尝试：
脚本-c zsh

哪些可能会迫使它启动一个新的zsh shell并让它来源您的zsh配置文件。

The UNIX "/usr/bin/script" command will create a running transcript of your shell session (see "man script" for more info).

However, when inside a script instance, it seems to forget the parent shell's env vars, aliases, etc.

The following example demonstrates how the "ll" alias I define is ignored inside "script":

zsh> mkdir temp
zsh> cd temp

zsh> alias "ll=ls -alF"

zsh> ll
total 24
drwxr-xr-x   2 me   mygroup    4096 Feb 18 13:32 ./
drwxr-xr-x  28 me   mygroup    8192 Feb 18 13:32 ../

zsh> script a.out
Script started, file is a.out

$ ll

zsh: command not found: ll

$ exit
Script done, file is a.out

zsh> ll
total 32
drwxr-xr-x   2 me   mygroup    4096 Feb 18 13:32 ./
drwxr-xr-x  28 me   mygroup    8192 Feb 18 13:32 ../
-rw-r--r--   1 me   mygroup     182 Feb 18 13:32 a.out

So, how can I get the "script" process to inherit the env settings from the parent shell?

[EDIT:] Okay, env vars are not forgotten. Just the aliases. Re-sourcing the .profile or something would work... but how can I make that happen automatically?

解决方案

It works OK when I start it under bash. Maybe there's something in your zsh configuration that's mucking it up, or it's not sourcing your zsh's startup files. You could try: script -c zsh

Which may force it to start a new zsh shell and have it source your zsh config files.
