Bash if statements in one line
I have the following bash code, and wondering if it is possible (and a good idea) to write the if statements in one line.

Code:
# Run raytrac on the sound speed model.
if [ $hasArgumentRytr -eq 1 ]; then
  $bashPath/raytrac.bash -fcmd=$fcmd.cmd
fi

# Plot the travel times and ray paths.
if [ $hasArgumentPlotryxt -eq 1 ]; then
  $bashPath/plotryxt.bash -fry=$fcmd.ry -fxt=$fcmd.xt
fi

# Remove source-receiver data exceeding dsrmx, Mm.
if [ $hasArgumentRmsrdist -eq 1 ]; then
  $bashPath/removeSRDist.bash -fry=$fcmd.ry -fxt=$fcmd.xt -dsrmx=$dsrmx
fi

# Plot ray paths and travel times.
if [ $hasArgumentPlotryxt -eq 1 ]; then
  $bashPath/plotryxt.bash -fry=$fcmd-dsr$dsrmx.ry -fxt=$fcmd-dsr$dsrmx.xt
fi

mysql_find_rows

MYSQL_FIND_ROWS 					       MySQL Database System						   MYSQL_FIND_ROWS

NAME

       mysql_find_rows - extract SQL statements from files

SYNOPSIS

       mysql_find_rows [options] [file_name ...]

DESCRIPTION

       mysql_find_rows reads files containing SQL statements and extracts statements that match a given regular expression or that contain USE
       db_name or SET statements. The utility expects statements to be terminated with semicolon (;) characters.

       Invoke mysql_find_rows like this:

	   shell> mysql_find_rows [options] [file_name ...]

       Each file_name argument should be the name of file containing SQL statements. If no file names are given, mysql_find_rows reads the
       standard input.

       Examples:

	   mysql_find_rows --regexp=problem_table --rows=20 < update.log
	   mysql_find_rows --regexp=problem_table  update-log.1 update-log.2

       mysql_find_rows supports the following options:

       o   --help, --Information

	   Display a help message and exit.

       o   --regexp=pattern

	   Display queries that match the pattern.

       o   --rows=N

	   Quit after displaying N queries.

       o   --skip-use-db

	   Do not include USE db_name statements in the output.

       o   --start_row=N

	   Start output from this row.
