Multiple commands using ipcBeginProcess

ajayghoshmv

Hi,

I am trying to use "sed -e 's " from SKILL code to edit unix file "FileA", to replace 3 words in the 2nd line.

How to run below multiple commands using  ipcBeginProcess, Should I use ipcWait or ipcCloseProcess ?

Using && to combine , will that work as I have to work serially on each command. ?

With below code only the first command gets executed. Please advise.

FileA="/user/tmp/text1.txt"

sprintf(Command1 "sed -e '2s/%s/%s/g' %s > %s" comment1 get(form concat("dComment" RDWn))->value FileA FileA)
cid = ipcBeginProcess(Command1)


sprintf(Command2 "sed -e '2s/%s/%s/g' %s > %s"  Time getCurrentTime() FileA FileA)
cid1 = ipcBeginProcess(Command2)


sprintf(Command3 "sed -e '2s/%s/%s/g' %s > %s"  comment2 get(form concat("Duser" RDWn))->value FileA FileA)
cid2 = ipcBeginProcess(Command3)

Thanks,

Ajay

    Hi Ajay,

    One way to make your life easier would be to use perl's "edit in place" feature,- assume you want to replace 'red' against 'green' in FileA you might go like this:

    ipc = (ipcBeginProcess (strcat "perl -i -p -e 's/red/green/g' /" FileA))
    (ipcWait ipc)

    The (ipcWait) waits for the perl child process to return - so when it comes back you can be sure the file is modified.

    Hi Max,

    Thank you for the input. Perl helped in my code.

    Regards
