Below is the way to do it.

MIGRATION_CONFIG_FILE="$(dirname $(dirname $(readlink $0)))"/$CONFIGURATION_FILE.

Shell script to connect postgress in a loop

i=211
while [ $i -le 250 ]
do
folder="psr-pub-$i"
echo "Starting processing $folder."
./svnmapping.sh $folder
echo "Done with $folder"
i=`expr $i + 1`
done


projectName=$1
userId="user1308"

DBConnect="psql -d psrdb -U psruser --tuples-only --single-line"

date=`date +"%F %T"`
projId=`echo "select id from project where path='projects.$projectName'" | $DBConnect`
projId=`echo $projId`

parent_folder_id=`echo "select id as parent_folderid from folder where path = 'scm' and project_id='$projId'" | $DBConnect`
parent_folder_id=`echo $parent_folder_id`

nextscm_id_query="select max(substring(id from (char_length('reps')+1))) from scm_repository"
primaryId_query="select id from objecttype where application='Scm' and name='Repository'"
secondaryId_query="select id from objecttype where application='Scm' and name='Commit'"

nextscm_id=`echo $nextscm_id_query | $DBConnect`
nextscmId=`echo $nextscm_id`
nextscmId=reps`expr $nextscmId + 1`
primaryId=`echo $primaryId_query | $DBConnect`
primaryId=`echo $primaryId`
secondaryId=`echo $secondaryId_query | $DBConnect`
secondaryId=`echo $secondaryId`

insertscm="insert into scm_repository values('$nextscmId', 'exsy1002', '/svnroot/$projectName', 'f')"
insertfolder="insert into folder values ('$nextscmId', 'scm.$projectName', '$projectName', '$projectName', '100', '$date+05:30', '$date+05:30','f', '$primaryId', '$secondaryId', '$userId', '$userId', '$parent_folder_id', '$projId', '0')"

scm=`echo $insertscm | $DBConnect`
fol=`echo $insertfolder | $DBConnect`

echo $scm" "$fol

Extract total number of requests hits

Below is the command to calculate no of time projects accessed using the url. The informations are retrieved from log file where all the requests are logged.

cut -d ' ' -f 7 ssl_request_log |grep '/sf/'|cut -d '/' -f 3|sort|uniq -c

cut -d ' ' -f 7 ssl_request_log |grep '/sf/'|sort|uniq -c

About Zenity, a linux command.

Need GTK+ support for the command or shell. Yes this is the right command. It's almost belong to similar family like Xdisplay, display, cDisplay.

Try this, it's awesome. I do no whether it's inbuilt in redhat but it's there in ubuntu.

Some quick cracks on that.

To get the calendar !
zenity --calendar
To get the input from the user !
zenity --entry
To get Yes or No
zenity --question --text "Do you need to proceed reading?"

Use the ouput of the above command to input of another command using echo $?.

The echo$? returns status of the previous command.

answer=`zenity --question --text "You appear to have an AMD64 architecture. Do you want to install the 64-bit version of Songbird?"; echo $?`

if [ $anw = 0 ] ; then
....
....
....
fi

I've missed this command lot or else I would've used in most of my scripting languages to get the user inputs :)

Needed shell script to compile and run java files.

#Let's start building the classpath with existing jars & libs.
THE_CLASSPATH=
for i in `ls *.jar`
do
THE_CLASSPATH=${THE_CLASSPATH}:${i}
done

# Let's compile all the java file.

for i in `find . -name '*.java'`
do
echo "Compiling $i"
javac -cp $THE_CLASSPATH $i
done

# invoke the main function.

java -cp .:$THE_CLASSPATH $CLASSNAME$
unset THE_CLASSPATH

To set classpath in linux

Simple tips, tought it will be useful

CLASSPATH=*.class:$CLASSPATH
export CLASSPATH
