I wasn't doing it that way, though. It was more like your following example, but without the backslashes and new lines.
I changed it to look closer to your example, but I still get the same result of 32512 for the system call. > (command file1; \ > command file2 | skip1; \ > ... > command file1066 | skip1 ) | mpeg2enc I think so. Here is how it looks: (lav2yuv +p /vcdtemp/lump/_cd11_dong_bei_and_HK_1of6___dscf0003.avi | yuvfps -v 0 -r 25:1 | yuvscaler -v O -O SVCD ; \ jpeg2yuv -v 0 -I p -f 25 -n 25 -j /vcdtemp/lump/_cd11_dong_bei_and_HK_1of6___dscf0004.jpg | yuvfps -v 0 -r 25:1 | yuvscaler -v 0 -O SVCD | /vcdtemp/strip_1.sh ; \ jpeg2yuv -v 0 -I p -f 25 -n 25 -j /vcdtemp/lump/_cd11_dong_bei_and_HK_1of6___dscf0005.jpg | yuvfps -v 0 -r 25:1 | yuvscaler -v 0 -O SVCD | /vcdtemp/strip_1.sh ; \ . . . many, many, many lines later (there are 1062 files in total) . . . lav2yuv +p /vcdtemp/lump/_cd11_dong_bei_and_HK_6of6___dscf0341.avi | yuvfps -v 0 -r 25:1 | yuvscaler -v O -O SVCD | /vcdtemp/strip_1.sh ; \ jpeg2yuv -v 0 -I p -f 25 -n 25 -j /vcdtemp/lump/_cd11_dong_bei_and_HK_6of6___dscf0342.jpg | yuvfps -v 0 -r 25:1 | yuvscaler -v 0 -O SVCD | /vcdtemp/strip_1.sh ) | mpeg2enc -v 0 -f 4 -o /vcdtemp/sum.m2v (n.b. your skip is my strip) > then the limit is the amount of space (and your patience for the > shell to parse the script ;)) available. It does take a while.

I don't think so. But, you can determine this more accurately from above. ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
