When you deploy your software, do you also have a common directory structure associated with it? For instance, if I were to deploy to /home/my-user, would there be common directories under /home/my-user such as sh, log, bin, files? If so, you could develop a common approach to deployment by having your user enter in the common path to the directory.

For example:

#My Deployment Script

echo "Enter Deployment Directory"
read DEPLOY_DIR

if [ ! -d $DEPLOY_DIR ]
then
echo "$DEPLOY_DIR Not A Directory"
exitt 1
fi

export UNIX_ENV=$DEPLOY_DIR

. $UNIX_ENV/envFile #Source in the environment file

#envFile
#Add all path variables to the env file so
#that you never have to change a path #again!

export SH_PATH=$UNIX_ENV/sh
export BIN_PATH=$UNIX_ENV/bin
export LOG_PATH=$UNIX_ENV/log

If this is not an option, then you can used sed to change all of the paths based upon user input. There will be a little effort to ensure your changing the correct line in each file. This can easly be overcome by tagging the line in each file that you want to have changed. Make sure that before you change your original file that you make a backup!

trace-cmd-check-events

TRACE-CMD-CHECK_EV(1)													     TRACE-CMD-CHECK_EV(1)

NAME

       trace-cmd-check-events - parse the event formats on local system

SYNOPSIS

       trace-cmd check-events [OPTIONS]

DESCRIPTION

       The trace-cmd(1) check-events parses format strings for all the events on the local system. It returns whether all the format strings can
       be parsed correctly. It will load plugins unless specified otherwise.

       This is useful to check for any trace event format strings which may contain some internal kernel function references which cannot be
       decoded outside of the kernel. This may mean that either the unparsed format strings of the trace events need to be changed or that a
       plugin needs to be created to parse them.

OPTIONS

       -N - Don't load plugins

SEE ALSO

       trace-cmd(1), trace-cmd-record(1), trace-cmd-report(1), trace-cmd-stop(1), trace-cmd-extract(1), trace-cmd-reset(1), trace-cmd-split(1),
       trace-cmd-list(1), trace-cmd-listen(1), trace-cmd-start(1)
