The main stumbling block with splitting paths in Bash is converting a relative path into an absolute one.

Searching the Internet I found many partial solutions, but none was entirely satisfactory. There may be a better solution out there, but I didn’t find it.

For example

ABSPATH="`realpath "${RELPATH}"`"

does work, but

• <realpath> may not be included in a standard distribution
• this only works for existing files

Alternatively, there’s

DIRABSPATH="`cd ${DIRRELPATH}; pwd`"

or

FILEABSPATH="`cd \`dirname "${FILERELPATH}"\`; pwd`/`basename "${FILERELPATH}"`"

but again

• these only work for existing directories or files in existing directories respectively

Therefore, I propose another, but still imperfect, solution. First, in your script, define a function:

function abspath
{
  RELPATH="${1}"
  PYTHONPROG="import os; print os.path.abspath(\"${RELPATH}\")"
  ABSPATH="`python -c \"${PYTHONPROG}\"`"
  echo ${ABSPATH}
}

This may then be called thus:

ABSPATH="`abspath ${RELPATH}`"

The problem with this is:

• it requires Python

On the other hand

• it works whether or not the path already exists

To further split the parts of a path, here are some further commands for a Bash script:

FILERELPATH="${1}"
FILEPATH="`abspath ${FILERELPATH}`"
FILEDIR="`dirname "${FILEPATH}"`/"
FILENAME="`basename "${FILEPATH}"`"
FILEBASE="${FILENAME%.*}"
FILEEXT="${FILENAME:${#FILEBASE}}"

Thus the input

~/myproject/splitpath.sh.tmpl

might result in

FILEPATH = /home/Rob/myproject/splitpath.sh.tmpl
FILEDIR = /home/Rob/myproject/
FILENAME = splitpath.sh.tmpl
FILEBASE = splitpath.sh
FILEEXT = .tmpl

Note that:

${FILEPATH} == ${FILEDIR}${FILENAME}
            == ${FILEDIR}${FILEBASE}${FILEEXT}

and

• an empty extension is handled correctly
• if the file path is a directory, this doesn’t quite work, even if a trailing slash (/) is provided

An alternative line for the file base above is

FILEBASE="${FILENAME%%.*}"

The former results in making the base as long and the extension as short as possible, whereas the latter works conversely.

Running a simple script over a file containing a list of basic English words revealed the following (strict) ‘upwords’ and ‘downwords’, i.e. words with alphabetically or reverse-alphabetically ordered letters.

Example usage is as follows. This can be varied in many ways to suit the project:

• main low-risk development takes place on the trunk
• major maintenance and bug fixes take place on  a feature branch to reduce impact on other developers; that is integrated to the trunk in a controlled and agreed fashion
• releases and tags are organised hierarchically to reduce clutter at lower levels
• for releases up to the first stable release, the trunk (at the head or otherwise) is branched to a release version branch; merging or un-merging cherry-picked revision could take place; version information and release notes might be updated; the tag is made from the branch
• for maintenance or upgrade releases thereafter, the trunk is branched to a maintenance branch for isolated maintenance work; the maintenance branch is branched to a release version branch; version information and release notes might be updated; the tag is made from the release branch; maintenance work is reintegrated to the thunk
• scripts, developer utilities and other material not associated with a particular branch could be placed in an auxiliary directory

To output a message to the error stream in a batch file, simply do this:

echo your message text 1>&2

Similar syntax may be used in Bash shell scripts:

echo "your message text" 1>&2

This is useful for still outputting error messages produced by batch files or Bash scripts whose result output might be piped into a file.

For example, in the script, have lines such as

echo result output
echo syntax error: missing parameter 1>&2

then, a command such as

call script.bat > result.stdout.txt

still shows any errors on the screen (the result output is redirected into the file); conversely, the command

call script.bat 2> report.stderr.txt

redirects the errors into a file; the command

call script.bat > result.stdout.txt 2> report.stderr.txt

records the result and errors, if any, in separate files; and the command

call script.bat > combined.stdstm.txt 2>&1

combines all the output into a single file.

The special device nul in DOS (or /dev/null in Bash) may be used to throw away output. So, for example, the command

call script.bat > nul

shows the errors on the screen, but throws away the result output.

To test whether a directory (or “folder”) is empty, the code

if exist "%dir%\*.*" (
  echo %dir% is non-empty
) else (
  echo %dir% is empty
)

does not work; it always reports “non-empty”.

The trick

( dir /b /a "%dir%" | findstr . ) > nul && (
  echo %dir% non-empty
) || (
  echo %dir% empty
)

using conditional execution, however, does work.

Here is an example file using this trick in a separate “function”:

@echo off

goto :main

REM *** === Function "Test" ===================================================

:test
if not "%1" == "" (
  if exist "%1" (
    ( dir /b /a "%1" | findstr . ) > nul && (
      echo %1 non-empty
    ) || (
      echo %1 empty
    )
  ) else (
    echo %1 missing
  )
) else (
  echo error: no parameter
)
goto :EOF

REM *** === Main ==============================================================

:main

call :test path\to\some\directory

I had a problem in JSP and JSTL where I could not get a core variable to contain the content of an XML XPath expression.

Following a combination of reading a book, searching the Internet and speaking to a colleague, I found two solutions to my problem, but unfortunately not an answer to the question of why my original code does not work.

Here is a code: fragment

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
    "http://www.w3.org/TR/html4/loose.dtd">

<html>
<%@ page contentType="text/html; charset=UTF-8" %>

<%@ taglib uri="http://java.sun.com/jsp/jstl/xml" prefix="x" %>

<head>
  <title>JSTL / JSP test</title>
</head>

<body>

<%--c:import url="/xml_files/document.xml" var="url"/>
<x:parse xml="${url}" var="doc" scope="page" /--%>

<x:parse var="doc" scope="page">
  <root_element>
    <more_elements>
      <element_name>the element value</element_name>
    </more_elements>
  </root_element>
</x:parse>

<table>
  <tr>
    <td>This doesn't work; why?</td>
    <x:set var="element_value1" scope="page"
        select="string($doc/root_element/more_elements/element_name/text())"/>
    <td><c:out value="${element_value1}"/></td>
  </tr>
  <tr>
    <td>This does work</td>
    <x:set var="element_node2" scope="page"
       select="$doc/root_element/more_elements/element_name"/>
    <x:set var="element_value2" scope="page"
        select="string($element_node2/text())"/>

  </tr>
  <tr>
