4. Three commonly used formats for sending letters
mail -s test [email protected] #In the first method, you can use the current shell as an editor. After editing the content, Ctrl-D can enter the CC, which can be separated by a comma, and sent after the carriage return.
echo "mail content"|mail -s test [email protected] #The second method, use the pipeline
mail -s test [email protected] <file #The third method, use the content of the file as the mail content to send a letter
Send attachments
If there is no uuencode command in your system, please install sharutils first (yum install sharutils).
uuencode requires two parameters. The first is the file(s) you want to send. Of course, this can also be done using a pipeline, and the second Is the displayed file name
uuencode 1.txt 1.txt | mail -s test2 [email protected] (text file under linux is best to be unix2dos first)
tar zcf – /tmp/1/ |uuencode 1.tgz | mail -s test1 [email protected]
Both attachment and message body
Write your email first, such as mymail, then
uuencode <attachment file name> <attachment file name> >> mymail
or cat <attachment file name> | uuencode <attachment file name> >> mymail
and edit your mymail file, in front Write the body of the letter. Then send it out.
Actual operation: echo'hello zhengwen
' >zhengwen.txt
cat 1.gif | uuencode 1.gif>>
zhengwen.txt cat zhengwen.txt |mail -s test1 [email protected]
Send the letter to one or more email addresses.
mail -s title -c user1 user2 <mail.txt
mail -s biaoti [email protected] -c [email protected] -b [email protected] <1.txt
Check whether the sent e-mail is sent, or is stuck in the mail server.
