Can't set From using mail command in bash - bash

I am at my wits end....
All I want to do is set the From using a command line mail in a script.
I have tried mutt, mail, mailx...
Here is on command I tried:
echo "Once again" | mail -s "Maybe this time" -A file.csv stevec#isonas.com -r 'John <john#company.com>' -a From:John\<john#company.com\>
And another:
mutt -e "set from=john#company.com"...
And another:
mutt -e "set from=john#company.com" -e "set realname=John"
My /etc/mailname has the name I want too. I also tried configuring a muttrc file and that doesn't work
And another try:
mailx -r "DoNotReply#company.com" -a "From:DoNotReply#company.com" -s "Subject" -A "/opt/file.csv" "john#anothercompnay.com" <<< Some Text
Any ideas I can try?

I assume that you have configured john#company.com in an extra configuration file (~/.mutt/accounts/john) which you usually source as soon as you start using it in mutt. Simply load that configuration.
echo "mail body" | mutt -e "source ~/.mutt/accounts/john" -e "set content_type=text/plain" -s "subject" -- peter#company.com
An account specific configuration file may look like this (msmtp is used in this case to send mails):
set sendmail = "/usr/bin/msmtp -a Mailbox"
set realname = "John"
set from = "john#company.com"
set mbox_type = Maildir
set folder = "/home/john/.mails"
set spoolfile = "+Mailbox/INBOX"
set record = "+Mailbox/Sent"
set postponed = "+Mailbox/Drafts"

How can I disable * expansion in a script?

I have a strange problem - possibly I'm just going blind. I have this short script, which replaces the string #qry# in the here-document with a select statement in a file and then pipes it to mysql:
#!/bin/bash
if [[ "$1" == "-h" ]]
then
echo "sqljob [sqlfile] [procnm] [host] [database] [config file]"
echo " sqlfile: text file containing an SQL statement"
echo " procnm: name that will given to the new, stored procedure"
echo " host: hostname of IP address of the database server"
echo " database: the procedure will be created here"
echo " config file: default configuration file with username and password"
exit
fi
infile=$1
procnm=$2
hn=$3
pn=$4
db=$5
mycfg=$6
{
set -o noglob
sed -e "s/#qry#/$(echo $(cat $infile))/g" <<!
drop procedure if exists $procnm;
delete from jobs where jobname="$procnm";
insert into jobs
set
notes="SQL job $procnm",
jobname="$procnm",
parm_tmpl='int';
delimiter //
create procedure $procnm(vqid int)
begin
call joblogmsg(vqid,0,"$procnm","","Executing #qry#");
drop table if exists ${procnm}_res;
create table ${procnm}_res as
#qry#
end//
delimiter ;
!
} | mysql --defaults-file=$mycfg -h $hn -P $pn $db
However, when the select contains *, it expands to whatever is in the directory even though I use noglob. However, it works from the command line:
$ set -o noglob
$ ls *
What am I doing wrong?
Edit
Block Comments in a Shell Script has been suggested as a duplicate, but as you will notice, I need to expand ${procnm} in the here-doc; I just need to avoid the same happening to select *.
I suspect it is because the construct echo (cat). The echo command gets the * from the cat command and the shell in which it runs expands it. In that shell set noglob is not active.
Try leaving the echo away: /$(cat $infile)/, in the end that is the data you need; then there is no extra glob expansion by a shell.

Save an email attachment automatically to map with qmail and reformime

Save an email attachment automatically to map with qmail and reformime
I'm trying to move attachment automatically to another locatie with the dot-qmail file.
My .qmail file
#------------------------------------------------------------
| condredirect pdf-junkmail headermatch 'X-Spam-Status: Yes'
| reformime -X /bin/sh -c "if [ "\${FILENAME#*.}" == "pdf" ]; then cat > /home/users/name/home/$(date +%Y%m%d)_\$FILENAME; fi"
# Forward not set
# Vacation Message not set
./Maildir/
This works for a simple mail with one attachment. My questions:
How can I also move the mailmessage that belongs to this attachment to a mailbox named "done".
Above command doesn't work with multiple attachments in one mailmessage? How can I ajust this line to work for multiple attachments?
This doesn't work if the filename contains multiple dots like "how.areyou.pdf"
Thanks for the help
Here is a featured implementation for your problem.
First save and set permissions to this bash script for your user.
You will need to call it from your .qmail file:
extract-pdf-attachments.sh
#!/usr/bin/env bash
# This script process mail message attachments from stdin MIME message
# Extract all PDF files attachments
# and return the MIME message to stdout for further processing
# Ensure all locale settings are set to C, to prevent
# reformime from failing MIME headers decode with
# [unknown character set: ANSI_X3.4-1968]
# See: https://bugs.gentoo.org/304093
export LC_ALL=C LANG=C LANGUAGE=C
# Setting the destination path for saved attachments
attachements='/home/users/name/home'
trap 'rm -f -- "$mailmessage"' EXIT # Purge temporary mail message
# Create a temporary message file
mailmessage="$(mktemp)"
# Save stdin message to tempfile
cat > "$mailmessage"
# Iterate all MIME sections from the message
while read -r mime_section; do
# Get all section info headers
section_info="$(reformime -s "$mime_section" -i <"$mailmessage")"
# Parse the Content-Type header
content_type="$(grep 'content-type' <<<"$section_info" | cut -d ' ' -f 2-)"
# Parse the Content-Name header (if available)
content_name="$(grep 'content-name' <<<"$section_info" | cut -d ' ' -f 2-)"
# Decode the value of the Content-Name header
content_name="$(reformime -c UTF-8 -h "$content_name")"
if [[ $content_type = "application/pdf" || $content_name =~ .*\.[pP][dD][fF] ]]; then
# Attachment is a PDF
if [ -z "$content_name" ]; then
# The attachment has no name, so create a random name
content_name="$(mktemp --dry-run unnamed_XXXXXXXX.pdf)"
fi
# Prepend the date to the attachment filename
filename="$(date +%Y%m%d)_$content_name"
# Save the attachment to a file
reformime -s "$mime_section" -e <"$mailmessage" >"$attachements/$filename"
fi
done < <(reformime < "$mailmessage") # reformime list all mime sections
cat <"$mailmessage" # Re-inject the message to stdout for further processing
Then in you .qmail:
#------------------------------------------------------------
| condredirect pdf-junkmail headermatch 'X-Spam-Status: Yes'
| bash /path/to/extract-pdf-attachments.sh | condredirect done true
# Forward not set
# Vacation Message not set
./Maildir/

Multiple Aliases for different commands

I am attempting to create a bash script that will ssh into remote network devices, run commands based on the model, and then save the output.
At this time I have my expect file that contains the following:
#!/user/bin/expect
set pw xxxxxxx
set timeout 5
spawn ssh [lindex $argv 0]
expect "TACACS Password:"
send "$pw\r"
interact
I have my .sh file that contains variables which allows me to login to separate "host" files based on Model type. It contains:
shopt -s expand_aliases
fpath="path where scripts are located"
opath="MAC_Results.log"
for i in $( cat $fpath/3560hosts )
do
expect script.exp $i >> "$opath"
done
When I run my .sh, everything operates as expected. My issue lies in I do not know how to call my aliases. I have edited the .bashrc and have sourced it. The .bashrc contains the following:
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# User specific aliases and functions
alias loc3560="term length 0; show mac address-table | ex Gi|CPU|Po; exit"
alias locx="term length 0; show mac address-table | ex Gi[1|2]/1|CPU|Vl99|Po1|dynamic|system; exit"
I have also added the aliases within my .sh aliases. but cant seem to get the right syntax. I have tried the following variations but with no success...
for i in $( cat $fpath/3560hosts )
do
expect script.exp $i $loc3560 >> "$opath"
done
and
for i in $( cat $fpath/3560hosts )
do
expect script.exp $i >> "$opath";
$loc3560
done
Would appreciate any suggestions on where to put these to call to them.
Unfortunately I was not able to figure out how to call my functions or aliases within my main .sh script. With that though I found a way to achieve what I wanted via my expect file . Code listed below and it works like a charm. My subdirectory of 21 files has now been reduced to 3!
set loc3560 "show mac address-table | ex Gi|CPU|Po
exit"
set locx "show mac address-table | ex Gi1/1|Gi2/1|CPU|Vl99|Po1|dynamic|system
exit"
set loc4500 "show mac address-table | ex 1/3|1/5|Port-channel|Switch|1/1|1/2|dynamic|system
exit"
set loc888 "show mac-address-table | i FastEthernet
exit"
set loces2 "show mac address-table | i Fa0
exit"
spawn ssh [lindex $argv 0]
expect "TACACS Password:"
send "$pw\r"
expect "#"
send "$ver\r"
expect {
"C3560-IPSERVICESK9-M" {
send "$loc3560\r"
exp_continue
}
"CAT3K_CAA-UNIVERSALK9" {
send "$locx\r"
exp_continue
}
"C3750E-UNIVERSALK9-M" {
send "$locx\r"
exp_continue
}
"CISCO888-SEC-K9" {
send "$loc888\r"
exp_continue
}
"bootflash:/cat4500e" {
send "$loc4500\r"
exp_continue
}
"SM-ES2-24" {
send "$loces2\r"
exp_continue
}
}
interact
expect "#"
send "exit\r"
end
From here I am then able to call my script and output it to a log file in my directory via:
./script.sh >> Results.log

Salt within for loop using incremental variable to set value in sed command

What I'm trying to do is have salt set an internal host ip based on the current value of $i from the for loop. I've tried the following but was unsuccessful at modifying a network script that contains this line: 192.168.200.100 which resides in all 39 nodes.
for ((i=2; i<=30; i++)); do sudo salt -L "host$i.dev.mysite.com" cmd.run "sed -i "s/192.168.200.100/192.168.200.$i/" /etc/sysconfig/network-scripts/ifcfg-bond1; done"
Results I am looking is to have each hostX.dev.mysite.com bond1 files modified from 192.168.200.100 to 192.168.200.2
host2.dev.mysite.com /etc/sysconfig/network-scripts/ifcfg-bond1 = 192.168.200.2
host3.dev.mysite.com /etc/sysconfig/network-scripts/ifcfg-bond1 = 192.168.200.3
host4.dev.mysite.com /etc/sysconfig/network-scripts/ifcfg-bond1 = 192.168.200.4
host5.dev.mysite.com /etc/sysconfig/network-scripts/ifcfg-bond1 = 192.168.200.5
host6.dev.mysite.com /etc/sysconfig/network-scripts/ifcfg-bond1 = 192.168.200.6
host7.dev.mysite.com /etc/sysconfig/network-scripts/ifcfg-bond1 = 192.168.200.7
etc...
Something like this?
for ((i=2;i<=30;i++)); do
sudo salt -L "host${i}.dev.mysite.com" cmd.run "sed -r -i \"s#([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)[0-9]{1,3}\$#\1$i#\" /etc/sysconfig/network-scripts/ifcfg-bond1"
done

SQUID3 - using multiple auth_param like basic_ncsa_auth & basic_ldap_auth

i tried to setup squid3 with multiple auth_param. Basically, the first choice should be basic_ldap_auth and if this doesnt return OK it should try basic_ncsa_auth with the same values. As far as i know squid doesnt support it however there is the possibility to use "external" ACL
auth_param basic program /usr/lib/squid3/basic_fake_auth
external_acl_type MultAuth %SRC %LOGIN %{Proxy-Authorization} /etc/squid3/multAuth.pl
acl extAuth external MultAuth
my "multAuth.pl"
use URI::Escape;
use MIME::Base64;
$|=1;
while (<>) {
($ip,$user,$auth) = split();
# Retrieve the password from the authentication header
$auth = uri_unescape($auth);
($type,$authData) = split(/ /, $auth);
$authString = decode_base64($authData);
($username,$password) = split(/:/, $authString);
# do the authentication and pass results back to Squid.
$ldap = `/bin/bash auth/ldap.sh`;
if ($ldap == "OK") {
print "OK";
}
$ncsa = `/bin/bash auth/ncsa.sh`;
if ($ncsa == "OK") {
print "OK";
} else {
print "ERR";
}
}
now i am trying to run with ncsa.sh and ldap.sh the "normal" shell command for these auth methods.
./basic_ldap_auth -R -b "dc=domain,dc=de" -D "CN=Administrator,CN=Users,DC=domain,DC=de" -w "password" -f sAMAccountName=%s -h domain.de
user password
and
./basic_ncsa_auth /etc/squid3/users
user password
Therefor i ran:
auth/ncsa.sh
#!/usr/bin/expect
eval spawn [lrange $argv 0 end]
expect ""
send [lindex $argv 1]
send '\r'
expect {
"OK" {
echo OK
exp_continue
}
"ERR" {
echo ERR
exp_continue
}
interact
with
./ncsa.sh "/usr/lib/squid3/basic_ncsa_auth /etc/squid3/users" "user password"
and i generate the following error:
couldn't execute "/usr/lib/squid3/basic_ncsa_auth /etc/squid3/users": no such file or directory
while executing
"spawn {/usr/lib/squid3/basic_ncsa_auth /etc/squid3/users} {user password}"
("eval" body line 1)
invoked from within
"eval spawn [lrange $argv 0 end]"
(file "./ncsa.sh" line 2)
Besides this error, i am not sure how to pass the variables (username & password) forward and i am also not sure how to answer the shell questions like for example the user & pw input for basic_ldap_auth .
Is there a nice way how to solve that? or any other good plan ?
thanks!
FWIW, the following script helped me transition from passwd based to LDAP based authentication.
Contrary to your requirements, my script acts the other way around: It first checks passwd, then LDAP.
