bash - "invalid or incomplete multibyte or wide character" when executing script by cron
提问by Daniel Gadawski
I've got a bash script sending an e-mail using mailx. Mailbox configuration is in .mailrc. I'm running it as a root:
我有一个使用mailx 发送电子邮件的bash 脚本。邮箱配置在 .mailrc 中。我以root身份运行它：

As you can see, it runs correctly.
如您所见，它运行正常。
However, there's a problem when I try to run this script using cron.
但是，当我尝试使用 cron 运行此脚本时出现问题。
Here's my /etc/crontab content:
这是我的 /etc/crontab 内容：
SHELL=/bin/bash
PATH=/usr/bin:/usr/sbin:/sbin:/bin:/usr/lib/news/bin
MAILTO=root
HOME=/root
#
# check scripts in cron.hourly, cron.daily, cron.weekly, and cron.monthly
#
-*/15 * * * * root test -x /usr/lib/cron/run-crons && /usr/lib/cron/run-crons >/dev/null
* * * * * root /root/lprojekt.sh >> /root/Desktop/log.txt
Each minute (it's just for debug now), root user get a mail:
每分钟（现在只是为了调试），root 用户收到一封邮件：

Are you sure it's LC_TYPE and not LC_CTYPE? The latter should be the correct spelling. What's the other values of the locale variable, POSIX or pl_PL.UTF-8? You can set environment variables directly in the crontab file, just like you do with SHELL etc. Try setting LC_CTYPE and/or LC_ALL and/or LANG to pl_PL.UTF-8. Or perhaps find and remove non-ASCII characters from your script and the data files it uses. – n.m.
你确定是 LC_TYPE 而不是 LC_CTYPE？后者应该是正确的拼写。区域设置变量 POSIX 或 pl_PL.UTF-8 的其他值是什么？您可以直接在 crontab 文件中设置环境变量，就像使用 SHELL 等一样。尝试将 LC_CTYPE 和/或 LC_ALL 和/或 LANG 设置为 pl_PL.UTF-8。或者从您的脚本及其使用的数据文件中查找并删除非 ASCII 字符。– 纳米
You're right, there are LC_CTYPE instead of LC_TYPE. Other variables are POSIX. I've added to script this line: export LC_CTYPE=pl_PL.UTF-8 and it works. Thank you very much for help! – Daniel Gadawski
你是对的，有 LC_CTYPE 而不是 LC_TYPE。其他变量是 POSIX。我已将这一行添加到脚本中： export LC_CTYPE=pl_PL.UTF-8 并且它有效。非常感谢您的帮助！— 丹尼尔·加达夫斯基
