Currently, ARG_MAX is set to: $ getconf ARG_MAX 65536 in syslimits.h. This is quite low compared to other OS (SunOS has 1MB IIRC, and OpenBSD 3.5 256K) and causes the "argument list too long" issues when for instance grep'ing in directories with lots of files. Last time the limit was upped was ten years ago: "Revision 1.4 / (download) - annotate - [select for diffs], Mon Aug 8 09:12:43 1994 UTC (10 years, 1 month ago) by davidg Branch: MAIN Changes since 1.3: +2 -2 lines Diff to previous 1.3 (colored) Increased ARG_MAX even further...to 64k bytes." Is there a reason for keeping ARG_MAX so low, or could it be increased to eg. 262,144 bytes? -- Juha
