这是我的测试bash脚本。我无法使其正常工作。我看到两个错误:
Use of uninitialized value $answer in chop at /usr/sbin/adduser line 589.
Use of uninitialized value $answer in pattern match (m//) at /usr/sbin/adduser line 590.
这是我的脚本:
#!/bin/bash
sudo adduser myuser << ENDX
password
password
First Last
Y
ENDX
exit 0
这是输出:
me@mycomputer$ ./adduser.sh
Adding user `myuser' ...

Is the information correct? [Y/n] me@mycomputer$
这是在Kubuntu 12.04 LTS上
$ bash --version
bash --version
GNU bash, version 4.2.25(1)-release (x86_64-pc-linux-gnu)
这是来自adduser的行(系统脚本-我未修改),带有两个相关行号的表示法:
for (;;) {
my $chfn = &which('chfn');
&systemcall($chfn, $new_name);
# Translators: [y/N] has to be replaced by values defined in your
# locale. You can see by running "locale yesexpr" which regular
# expression will be checked to find positive answer.
print (gtx("Is the information correct? [Y/n] "));
chop (my $answer=<STDIN>); <-- LINE 589
last if ($answer !~ m/$noexpr/o); <-- LINE 590
}
