[Digikam-users] Not completely but a bit off topic question: looking for texteditor with macro capabillity

Hi Sleepless,

That is my first answer to this list, but I've been playing with the
linux command line for quite some years now.

To use such a list, you can use "$(ls)", or "$(ls <directory>)"...

Let's say you want to copy from /mnt/data1/ to /mnt/data2/

${s} is your string (e.g. $(pwd), i.e. the directory you are in):

$ echo ${s} | sed -e "s#/mnt/data1\(/.*\)#\1#"

This line removes "/mnt/data1" from the string ${s}.

For this, you can do (from /mnt/data1/foto/digikam/ to
/mnt/data2/foto/digikam/):

$ for f in $(ls); do move ${f} $(pwd | sed -e "s#/mnt/data1\(/.*\)#\1/#"); done


For most batch jobs (dealing with files), you can use bash script,
either in one line like I wrote, or execute a file like this one
(which is easier to read):

$ cat batch.sh
#!/bin/bash
for f in $(ls)
do
    TARGET=$(pwd | sed -e "s#/mnt/data1\(/.*\)#\1/#")
    if [ ! -d ${TARGET} ]
    then
        mkdir -p ${TARGET}
    fi
    move ${f} ${TARGET}
done

Then (after a "chmod 755 batch.sh" to make it executable), you just
have to do this in the directory where your photos are:

$ ./batch.sh

Note that I added a test to create the directory in the target if it
is missing, and the one line command suppose that
/mnt/data2/foto/digikam already exists.

A better version would replace $(ls) with $(ls *.jpg) in case there
could be directories listed with $(ls).


sed is the key here (along with bash scripting). It stands for Simple
EDitor (simple does not mean easy here...), but it has no graphical
interface, it is always run the same way I did. You'll find it very
convenient if you learn how to use it. Note that some people will use
awk (I think) to do the same job.

I hope that helps.
