adding quotation marks in a string - nesting strings

lperktold over 14 years ago

Hello,

I would like to run a shell command and wait for it to finish before SKILL continues.

Assume I want to delete a directory hirachically, (I didn't find a hirachically delete command in SKILL) by running

ccmd = sprintf(strx "rm -r %s" run_directory)
csh(ccmd)

Thid works fine, but SKILL is not waiting for the csh command to finish. So I tried to use the inter process communication capability of SKILL:

ccmd = sprintf(strx "rm -r %s" run_directory)
cid = ipcBeginProcess( strcat("csh(\"" ccmd "\")" ) )
ipcWait(cid)

This code does not give me any errors or warnings but does also not delte the directory. I guess the basic problem comes with nesting of strings when running ipcBeginProcess(). The csh() command as well as the ipcBeginProcess() command expect a string as an argument. I tried to nest those two strings by using the quotation mark escape sequence. SKILL then produces a string like:

> strcat("csh(\"" ccmd "\")" )
"csh(\"rm -r /simulation/320MHz_1.2V_27deg\")"

It seems like the csh() command is not capable of interpreting its given string correctly? But this is just a guess.

Would appreciate any comments.

Enjoy Lunch,
Lukas

Not sure why csh("command") is not waiting (it does for me).

With ipcBeginProcess, you want to do ipcBeginProcess("rm -rf dir" ...) and not a command like "csh(rm -rf ...)" because that's not a valid UNIX command.
