You can always add the directories or folders that contain your commands files in PATH env variable, for example:

PATH=$PATH:/usr/bin ; export PATH

This will take care of it, or you can directly call the file by using its full path name in the script:

/usr/bin/mail

I get this when executing that:

machine:username:/home/username/data$ which mail
/usr/bin/mail

Then the "mail" function is available in /usr/bin

so, if i want to execute it from another location such as /usr/data/myscript.ksh, what do i need to do? do i need to declare it somehow in the script??

If the script on machine1 is sending thru a user that exists on machine1, the same user may not exist on machine2.  You may have to change the user that is sending the email on machine2.

in this case i would like to send directly from machine2, not making the call from machine1

Can you post your script that sends the email, at least that part of the script?  You can hide or obscure the email address you are using.

sure, it works perfectly on machine1, but not on machine2

#!/bin/ksh

MAIL_FILE="testfile.txt"

rm -f $MAIL_FILE



echo "From:ScriptTesol" > $MAIL_FILE
echo "To:Me LastName <mail@mycompany.com>" >> $MAIL_FILE
echo "Subject:Test eMail" >> $MAIL_FILE
echo "Content-Type: text/html" >> $MAIL_FILE
echo "<html>" >> $MAIL_FILE
echo "<body style='font-family:calibri;font-size:14px;'>" >> $MAIL_FILE
echo "<h2> Test email h2 </h2>" >> $MAIL_FILE


cat $MAIL_FILE|mail me@mycompany.com

Whe doing mail -v me@mycompany.com i get:


mail: illegal option -- v
mail: Usage: [-ehpPqr] [-f file] [-x debuglevel]
or      [-tw] [-m message_type] [-T file] [-x debuglevel] persons
or      [-x debuglevel]

ozoCommented:
I don't see me@mycompany.com as one of the options
what does
man mail
say?

celticianAuthor Commented:
In the funcion above the mail is being sent using that function and being set as parameter as its written.

I substituted 'sendmail' for 'mail'. Your script works perfectly sending to one email address and not at all sending to another one.  The mail server you are sending to or thru may make a difference also.
