Using valgrind to start a program that is started using a cryptic bash command

I have the following bashscript in my /opt/mydev folder

COMMAND=""

buildCommand2() {
    COMMAND=$COMMAND"--tab -e 'bash -c \"source ~/.bashrc; source ~/Desktop/developer/setup.bash; cd /opt/mydev/$1& $1/$1; bash\"' "
} 

buildCommand2 'MyFileManager'

Now /opt/mydev folder contains a folder named MyFileManager which contains an executeable named MyFileManager

When I run the above bash script, it starts up MyFileManager in a new tab.

I now want to run the executeable MyFileManager with valgrind

valgrind --leak-check=full \
         --show-leak-kinds=all \
         --track-origins=yes \
         --verbose \
         --log-file=valgrind-out.txt \
         ./MyFileManager/MyFileManager

How do I do this? I found the buildCommand2 quite cryptic

i typically use an additional (empty by default) variable, that injects valgrind (or gdb; or wine; or...) in the right place....

for whatever reasons i call it INTERPRETER, but pick your own better name...

COMMAND=""
: ${INTERPRETER:=""}

buildCommand2() {
    COMMAND=$COMMAND"--tab -e 'bash -c \"source ~/.bashrc; source ~/Desktop/developer/setup.bash; cd /opt/mydev/$1 & ${INTERPRETER} $1/$1; bash\"' "
}

buildCommand2 'MyFileManager'

than run your script with:

$ export INTERPRETER="valgrind --leak-check=full \
         --show-leak-kinds=all \
         --track-origins=yes \
         --verbose \
         --log-file=valgrind-out.txt"
$ mybuildcommand

or in one line:

$ INTERPRETER="gdb --args" mybuildcommand

notes:

  • the : ${INTERPRETER:=""} is effectively a no-op; it only serves to document the existence of the variable. you could use it to provide a default interpreter
  • you still have to provide the entire invocation of valgrind (or whatver) on the cmdline; this is by design (as I usually want different variants to be readily available)
  • i've just copy'n'pasted your script, even though it appears to have some syntax errors
