Top Forums UNIX for Dummies Questions & Answers BASH: Change alias to script to add a task Post 302488871 by SilversleevesX on Tuesday 18th of January 2011 03:40:39 PM
MySQL Found another way to do it.

I appreciate the suggestions. Likely as not I'll be coming up with some scripts very much like this one in the near future, so I'll keep this thread bookmarked.

What I failed to mention is, while I write the filenames I want into the "homeperm" or "curl -o" command, I usually paste in the source URLs from the clipboard of whatever OS I happen to be using. This gave me a bit of a headache just using $1 as input from the line, as curl only saw the filename as I typed it and didn't have anything for a URL. It wasn't until I echo'd what curl was getting for input that I gleaned what I was doing wrong.

Then I thought, "If there's a $1, shouldn't there be a $2? Single spaces are seen by BASH as a break, if not a delimiter, aren't they?" So I tried this line near the top of the script:
Code:
echo -e "$1 $2"

and invoked the script (with a standby alias, "homecourt"). Sure enough, the URL printed to stdout right after the filename as sure as dinner follows lunch. cUrl downloaded the file, and the code I had written to annotate the dates ran smooth as melted butter.

Here's the final script.
Code:
#!/bin/bash
actiondate=$(/usr/bin/date)
echo -e "$1 $2 $actiondate"
clockdate=$(date '+%d %B, %Y.')
myfile=$1
myurl=$2
curl -o $myfile $myurl
fulldate=$(stat -c %y $myfile)
shortdate=${fulldate%.*}
exiv2 -kM"set Exif.Image.DateTimeOriginal Ascii $shortdate" $myfile
exiv2 -kM"set Iptc.Application2.SpecialInstructions String Downloaded $clockdate" $myfile
exiv2 -kM"set Exif.Image.DocumentName Ascii $myurl" $myfile
echo -ne "File $myfile downloaded and annotated with date and time.\n\n"

Thanks again for the suggestions.

NAME
Template::Tools::tpage - Process templates from command line USAGE
tpage [ --define var=value ] file(s) DESCRIPTION
The tpage script is a simple wrapper around the Template Toolkit processor. Files specified by name on the command line are processed in turn by the template processor and the resulting output is sent to STDOUT and can be redirected accordingly. e.g. tpage myfile > myfile.out tpage header myfile footer > myfile.html If no file names are specified on the command line then tpage will read STDIN for input. The "--define" option can be used to set the values of template variables. e.g. tpage --define author="Andy Wardley" skeleton.pm > MyModule.pm See Template for general information about the Perl Template Toolkit and the template language and features.
