When running the command `strace -e trace=file man` I don't get filenames in the output. For all other executables I've tried, strace works fine. Only man has problems. The output in versions 4.8, 4.9, and 4.10 looks like execve("/usr/bin/man", ["man"], [/* 70 vars */]) = 0 access(0x7fcc920558d0, R_OK) = -1 ENOENT (No such file or directory) open(0x7fcc9205327d, O_RDONLY|O_CLOEXEC) = 3 open(0x7fcc922511b8, O_RDONLY|O_CLOEXEC) = 3 open(0x7fcc91e075a0, O_RDONLY|O_CLOEXEC) = 3 open(0x408ee3, O_RDONLY) = 3 open(0x7fff5b0acc40, O_RDONLY) = -1 ENOENT (No such file or directory) open(0x7fff5b0acc40, O_RDONLY) = -1 ENOENT (No such file or directory) open(0x7fff5b0acc40, O_RDONLY) = 4 What manual page do you want? In strace 4.7, it worked, but there were errors (again, these errors only show when tracing man, not other programs) : execve("/usr/bin/man", ["man"], [/* 70 vars */]) = 0 access(process_vm_readv: Operation not permitted "/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory) open(process_vm_readv: Operation not permitted "/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3 open(process_vm_readv: Operation not permitted "/lib64/libc.so.6", O_RDONLY|O_CLOEXEC) = 3 open(process_vm_readv: Operation not permitted "/usr/lib64/locale/locale-archive", O_RDONLY|O_CLOEXEC) = 3 open(process_vm_readv: Operation not permitted "/etc/man.conf", O_RDONLY) = 3 open(process_vm_readv: Operation not permitted "/usr/share/locale/en_US.UTF-8/man", O_RDONLY) = -1 ENOENT (No such file or directory) open(process_vm_readv: Operation not permitted "/usr/share/locale/en_US.UTF-8/LC_MESSAGES/man", O_RDONLY) = -1 ENOENT (No such file or directory) open(process_vm_readv: Operation not permitted "/usr/share/locale/en/man", O_RDONLY) = 4 What manual page do you want? In strace 4.6 and 4.5.20 (older versions untested) everything worked fine: execve("/usr/bin/man", ["man"], [/* 70 vars */]) = 0 access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory) open("/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3 open("/lib64/libc.so.6", O_RDONLY|O_CLOEXEC) = 3 open("/usr/lib64/locale/locale-archive", O_RDONLY|O_CLOEXEC) = 3 open("/etc/man.conf", O_RDONLY) = 3 open("/usr/share/locale/en_US.UTF-8/man", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/share/locale/en_US.UTF-8/LC_MESSAGES/man", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/share/locale/en/man", O_RDONLY) = 4 All of this testing was done on gentoo. |
