Mutt: set dynamic email signature from shell command output
I want to set my signature when mailing to the r-help mailing list to contain information about the R version I have currently installed. Creating a bash script that directly echoes the several lines that I want to have in my signature and executing that in the muttrc using backticks gives a “broken pipe” error.
One solution (I’m sure there are others, maybe better ones) is to make the shell script create a temporary signature file and echo the path to that file, then execute the shell script using backticks.
Shell script (don’t forget to chmod 744):
#!/bin/bash thesigfile=~/.mutt/rsig echo "Marianne Promberger PhD, King's College London http://promberger.info" > $thesigfile R --version | head -n 1 >> $thesigfile cat /etc/issue | head -n 1 | cut -d " " -f 1-2 >> $thesigfile echo $thesigfile
muttrc:
send-hook '~t r-help' 'set signature=`~/.mutt/signature_r-help`'
