Example iii - Email amongst Attachment from Linux

This is the most pop purpose of mailx dominance for me. I ever honor using this pick hold out it sending a file from Linux host to my windows host or writing scripts which sends electronic mail from a Linux machine. Until RHEL 5, my favorite agency to shipping an attachment inwards the electronic mail was yesteryear using the uuencode dominance e.g.

$ gzip -c log.txt | uuencode log.gz | shipping service -s "log file for `date`" abc@gmail.com


This dominance volition start compress the log.txt in addition to so volition shipping every bit attachment log.gz amongst dependent champaign "log file for a date" to abc@gmail.com, hither appointment volition hold out replaced yesteryear electrical current appointment because nosotros have got used `date`, which volition execute the appointment dominance in addition to pose its output here.

So, how produce nosotros solve this problem? Is in that location whatever other agency to shipping an electronic mail to attachment from RHEL half dozen hosts? Well, yes, we'll purpose the mailx dominance amongst -a flag, which is used to attach a file.

Here is the instance of a mailx dominance to shipping a file every bit an attachment to RHEL half dozen servers:

$ echo "mailx plant fine inwards RHEL 6" | mailx -s "texting" -a log.gz abc@gmail.com

This volition shipping an electronic mail amongst the torso every bit "mailx plant fine inwards RHEL 6" in addition to attachment every bit log.gz amongst the dependent champaign work every bit "texting".
