Hi,

I would need some help I`m pretty new to script writing...I`ll appreciete any help.. I need to find any files which has a big letter H on the end of the filename and put it in a new directory with todays date... I really dont know where to begin....

Thank you

Here is the script:

Code:

#!/bin/bash
SEARCHDIR="$1"
DESTDIR="$2"
list=$(find $SEARCHDIR -name "*[H$]" -print)
TODAY=$(date +"%d-%m-%y")
for f in $list
do
  d=$(dirname $f)
  ff=$(echo $f | awk -F"$d" '{ print $2}')
  [ ! -d $DESTDIR ] && mkdir -p $DESTDIR || :
  echo "Coping file: $f  => ${DESTDIR}${ff}-$TODAY"
  cp $f ${DESTDIR}${ff}-$TODAY
done

How to run?
Save above script as script.sh. Run following command:

Code:

chmod +x script.sh
./script.sh /tmp /data

Now script will look for any files which has a big letter H on the end of the filename in /tmp directory and copy all those files to /data directory with todays date.

Let me know..

wow.. thank you I`ll check it out right away... What should I need to change to for example I would always create a files named 0714filenameH.doc, 0715filenameH.doc etc. and I would like to find these files and make a folder from the first four char and put the mathcing files in that folder?
THank you once again, it was a great help, I just started to learn shell scripting and I`m a bit confused yet but I think it is a very powerfull stuff

This forum is great.

You need to modify script as per your requirements, as it does not make directories from first four characters.

It seems that variable ff stores actual filename, you need to pull first character from variable ff using cut command. For example following will print out first four character

Code:

echo 0714filenameH.doc | cut -b1-4

You can cut it from $ff variable and store to myDir variable:

Code:

mydir=$(echo $ff | cut -b1-4)

And then create a directory:

Code:

mkdir -p $mydir

Finally cp command would be:

Code:

cp $f ${mydir}${ff}-$TODAY

Hope you can assembled rest of script

I have managed the script to work like this:

#!/bin/bash
SEARCHDIR="$1"
DESTDIR="$2"
list=$(find $SEARCHDIR -name "*[HH]*.doc" -print)

for f in $list
do
d=$(dirname $f)
ff=$(echo $f | awk -F"$d" '{ print $2}')
mydir=$(echo $ff | cut -b1-5)
mkdir $DESTDIR/$mydir
echo "Coping file: $f => ${mydir}${ff}"
cp $f $DESTDIR/${mydir}${ff}
done

there is only one problem when there is a space in a folder name than it doesnt work like: " Some Directory Name"
Can it be fixed or the directory names must be one word?
Thank you

You need to read files on fly and copy them using some tricks:

Code:

#!/bin/sh
SEARCHDIR="$1"
DESTDIR="$2"

find $SEARCHDIR-name "*[HH]*.doc" -exec echo '{}'  \; | while read LINE
do
f="$LINE"
d=$(dirname "$f")
ff=$(echo "$f" | awk -F"$d" '{ print $2}')
mydir=$(echo $ff | cut -b1-5)
mkdir $DESTDIR/$mydir
Coping file: $f => $DESTDIR/${mydir}${ff}
cp "$f" "$DESTDIR/${mydir}${ff}"
done

hope this helps. Read above code carefully till u understand it very well...

I`ll study it from line to line..
I think it should be "find $SEARCHDIR -name "*[HH]*.doc" -exec echo '{}' \; | while read LINE"
Thank you for a great help... BTW do you know some online tutorials or books about shell scripting?
Thanks again

Regards, Norbert

Err

it should be $SEARCHDIR.. to be frank i just typed above script i.e. not tested on system... but i guess you got the logic
