Subject: for loop 'bad math expression'
Date: Mon, 29 Jan 2024 19:39:03 -0800	[thread overview]
Message-ID: <4c14e191-0605-4492-9f67-9a5b35ef132b@eastlink.ca> (raw)

Been reviewing and deleting old email backups but saving some:


for bb in *.eml~save*; do    # Error msg. points to this line.

     thunderbird -file $bb

     echo "\nFile: $bb: Press 's' to save, 'd' to delete or '^C' to quit."
     read -sk1 key

     case $key in
         d ) rm -v $bb ;;
         s ) mv -v $bb save-$bb ;;    # Rename so not viewed again.
         * ) errormsg "skipping file ..." ;;
     esac
done

... it's been working fine, done thousands.  But just now it threw me an 
error:

     global:20: bad math expression: operator expected at `CDF8.eml'

.... there's no such file.  They all have eight characters then '.eml':

    607 [2013-01-16--18:57] 48EE0E21.eml*
     694 [2013-01-16--18:57] 48ECE166.eml*
   10115 [2013-01-16--18:57] 48E4BB08.eml*

... like that.  And if saved:

    2842 [2013-01-16--18:57] save-48137E34.eml*
    3135 [2013-01-16--18:57] save-4812320B.eml*
    2278 [2013-01-16--18:57] save-48122AEC.eml*

Does anyone have the slightest clue what's going on here?
