The GNU Core Utilities implementation has limits on command line arguments. Arguments are nominally limited to 32 times the kernel's allocated page size. Systems with 4KB page size would thus have a argument size limit of 128KB.<ref>{{Cite web |title=How to get around the Linux "Too Many Arguments" limit |url=https://stackoverflow.com/questions/33051108/how-to-get-around-the-linux-too-many-arguments-limit |website=[[Stack Overflow|Stackoverflow]] |quote=With the coupling of ARG_MAX to ulim -s / 4 came the introduction of MAX_ARG_STRLEN as max. length of an argument [...] MAX_ARG_STRLEN is defined as 32 times the page size in linux/include/uapi/linux/binfmts.h [...] The default page size is 4 KB so you cannot pass arguments longer than 128 KB [...]}}</ref> For command-line arguments before kernel 2.6.23, the limits were defined at kernel compile time and can be modified by changing the variable <code>MAX_ARG_PAGES</code> in <code>include/linux/binfmts.h</code> file.<ref>{{Cite web |title=Linux_2_6_23 - Linux Kernel Newbies |url=https://kernelnewbies.org/Linux_2_6_23#Variable_argument_length |website=kernelnewbies.org}}</ref><ref>{{Cite web |title=kernel/git/torvalds/linux.git - Linux kernel source tree |url=https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b6a2fea39318e43fee84fa7b0b90d68bed92d2ba |website=git.kernel.org}}</ref> Newer kernels{{Which|date=January 2025}} limit the maximum argument length to 25% of the maximum stack limit (ulimit -s).
