如何将多行 output 重定向到 mailx 邮件正文？

Question

我正在尝试将命令的 output 重定向到 mailx。

if grep -B 1 line $curccrtpick; then
    grep -B 1 line $curccrtpick | head -2 > tempmsg
    mail -s "String found in $curccrtpick" -r test@test.com dummy@test.com < tempmsg
    #rm tempmsg
else
    echo nothing
fi

但它显示为附件形式的二进制文件（ATT00001.bin）

当我跑

tr -d '[\015\200-\377]' < tempmsg > tempmsg1

并将该文件重定向到 mailx 我收到 email 在一个衬里：

thefirstlinethesecondline

什么时候应该有两个

thefirstline
thesecondline

这是对我有用的逻辑。 使用 sendmail 似乎比使用 mailx 更合适。

if grep -B 1 Retry $curpickccsb; then
        stringLine1=$(grep -B 1 Line $curpickccsb | head -1)
        stringLine2=$(grep Line $curpickccsb | head -1)
        echo -e "String located in $curpickccsb. Sending email notification."
        echo -e "Content-Type: text/plain\r\nFrom: no-reply@domain.com\r\nSubject: String in $curpickccsb\r\n\r\n'$stringLine1'\r\n'$stringLine2'\r\n" | sendmail -f no-reply@domain.com test@domain.com
else
        echo -e "No errors located in $curpickccsb"
fi
