Help/How-to - simple UNIX script / gzip (beginner)
Hey all,

I would like to ask your help and sorry in advance for my ignorance since I am a complete beginner in this.

I need to create a UNIX script that will:
- scan a small number of folders and subfolders (see a similar file tree in the attachment)
- [maybe in the future store some useful data to use for populating an XML file]
- for each final folder (each of them contain 6 files), compress the 6 files in .tgz
[it may also need to either read a version.txt file or identify filename_v2 and use it instead of filename_v1]

Any help or link to appropriate tutorial/link with examples would be greatly appreciated.

Thank you very much in advance.

This is not clear to me. What are we "scanning" for?

Please give us a sample expected input and expected result

The input would be a folder that contains always 6 files. For example the file Documents/Vol1/A/Filename_v1/
would contain:

filename_v1.gif
filename_v1.html
filename_v1.xls
filename_v1.txt
filename_v1.vsd
filename_v1.docx

The output would be those 6 files compressed into one .tgz named:

PR-2012MonthDayHour-XXXX-V1-XXXXXX-filename.tgz


I am sorry if I fail to explain it well. Thanks in advance.

The attachment is hosed, cannot see it.
Code:
cd Documents/Vol1/A
find . -type d -exec basename  {} \; |
while read folder
do
   tar czvf /tmp/PR-2012`date +%m%d%H-XXXX-V1-XXXXXX-${folder}.tgz  $folder
done

This assumes that your version of tar supports the z options. It also assumes that when you cd to the directory: Documents/Vol1/A that you are in the directory immediately above Documents.

The compressed tar files end up in the /tmp directory.

Thank you very, very much for the quick reply. I am currently on another computer, as soon as I test it I will come back to thank you again!

There was an error message for "basename", not sure why (beginner)...

I received some more help and have this script:

Code:
#!/bin/sh
DST_DIR=/home/myname/Output/zipped
SRC_DIR=/home/myname/Input/Vol*/*
VERSION_FILE=version.txt
DT=`date +%Y%m%d%H`

for d in $SRC_DIR; do
        cd $d
        if [ -e $VERSION_FILE ]; then
                version=`cat $VERSION_FILE`
                if [ "$version" != "" ]; then
                        for f in `find . -path "*_v${version}"`; do
                                dirpath=`echo $d | rev | cut -d / -f1,2 | rev | sed 's/\//-/'`
                                cleanname=`echo $f | cut -d / -f 2 | cut -d _ -f 1`

                                tar zcvfp $DST_DIR/Proc_Sat-1-${DT}-S515-V${version}-OUNCL-P${dirpath}-${cleanname}.tgz $f > /dev/null 2>&1
                                if [ $? -ne 0 ]; then
                                        echo "error in backup" # add better error handling here
                                fi
                        done
                fi
        fi
done

# tar zcvfp Proc_Sat-1-${DT}-S515-V${version}-OUNCL.tar.gz Output/total

any ideas why it doesn't zip the files? It reads the folders and I receive no error message.

Thanks in advance!

Could you post the Operating System and version you are using. Many systems give you this output from the command
Code:
uname -a

....but yours may not. Feel free to obscure sections showing your host name/ipaddress or anything else that shows up that you wouldn't want to publish.
