[Lazarus] TProcess not mirroring terminal
Hi All, I'm using Lazarus 1.4 with Kubuntu 14.04 I've written a small GUI frontend for the rsync command. I assemble rsync command line switches and source and destination thru the TProcess paramlist and everything has been exactly mirrored by my program and when the exact same command is run through a terminal, it has worked perfectly for everything I want to do with rsync... ...until today. For the first time my output and the output from the same command line run in terminal work differently. Run it through terminal and the command is accepted, however running it through TProcess and rsync complains! The two outputs are listed below, the parameters passed are exactly the same. Anyone have an idea why this is so??? TERMINAL OUTPUT: juus@JuuSKub:~$ rsync -n -vshtplgiE --stats --modify-window=1 --progress /home/juus/Documents/** /media/juus/Lin1TB/BKactive skipping directory CodeBlocks skipping directory IntelliJ skipping directory qt f+ hackjs5.html f+ hackjs7.html f+ hackjs8.html Number of files: 3 (reg: 3) Number of created files: 3 (reg: 3) Number of deleted files: 0 Number of regular files transferred: 3 OUTPUT FROM MY PROGRAM rsync: link_stat /home/juus/Documents/** failed: No such file or directory (2) Number of files: 0 Number of created files: 0 Number of deleted files: 0 Number of regular files transferred: 0 :: Parameters passed to RSYNC: -n -vshtplgiE --stats --modify-window=1 --progress /home/juus/Documents/** /media/juus/Lin1TB/BKactive thanks, Julius -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Re: [Lazarus] TProcess not mirroring terminal
You can simply execute the shell and use its -c option to pass the rsync command with all options. Ok, thanks Michael. I will look into it.
