I investigated a bit, and that's what I found. Bash does not have a limit on line length or number of arguments. The operating system has a line length limit, and on my Linux box it is $ getconf ARG_MAX 2505728 In the case I reported, the line length was about 43*371+123=16076. Just for double check, ls on my entire directory takes 718 arguments without a problem: $ ls -1 * | wc -l 719 which is what one expects from the Gnu core utils. However /usr/lib/libreoffice/program/soffice has a limit of of 254 arguments (including the process file name), and the reason is that it is a shell script starting with !/bin/sh, which on my system means that dash is called. Experiments show that the limit on numer of arguments is imposed by Dash. In fact, if one calls /usr/lib/libreoffice/program/oosplash rather than /usr/lib/libreoffice/program/soffice then the limit disappears. I suggest that the shell scripts under /usr/lib/libreoffice/program use Bash rather than Dash, and that the libreoffice-common package is made to depend on the bash package. This is not a significant lack of efficiency, as the overhead of launching bash is negligible with respect to launching soffice from any point of view: cpu time, memory size, disk space occupied. -- Francesco Potortì (ricercatore) Mobile: +39.348.8283.107 ISTI - Area della ricerca CNR Teams: wnlabisti via G.
