trouble setting shell variable

trouble setting shell variable

[Jim Reimer - WA5RRH]

I'm trying to rename files based on what time it is *now*....

echo `date` | cut -b 25-28,12-13,15-16,18-19

gives me what I want to use for the file name, but I
can't figure out how to get it into a variable for use
later in the script when I rename the file.  I've tried

variablename=

followed by the above commands surrounded by quotes,
parenthesis, back tics, etc. - all produce syntax errors.

Somebody point me in the right direction.

Thanks,
-jdr-

Why are you echoing?  Simply pass the output of date to cut.

$ b=`date | cut -b 25-28,12-13,15-16,18-19`
$ echo $b

$ variablename=`echo \`date\` | cut -b 25-28,12-13,15-16,18-19`
$ vim ${variablename}

or

$ variablename=`date | cut -b 25-28,12-13,15-16,18-19`
$ vim ${variablename}

To make life simple use the formatting available with date.
eg.
$ variablename=`date +%d-%b-%Y`
$ echo ${variablename}
26-May-2002

Hope that answers your question.
