The file "badfile" does not exist. distillerror gives a condensed report that makes it easy to spot the problem. $ distillerror ls badfile ls: badfile: No such file or directory File Errors ----------- 0.0092 open /etc/ld.so.preload = -1 ENOENT 0.1033 lstat64 badfile = -1 ENOENT 0.1077 open /usr/share/locale/en_US/LC_MESSAGES/libc.mo = -1 ENOENT 0.1086 open /usr/share/locale/en/LC_MESSAGES/libc.mo = -1 ENOENT Misc Errors ----------- Error Codes ----------- ENOENT No such file or directory Last 8 Lines ------------ 0.1033 lstat64("badfile", 0x8055bdc) = -1 ENOENT 0.1047 write(2, "ls: ", 4) = 4 0.1062 write(2, "badfile", 7) = 7 0.1077 open("/usr/share/locale/en_US/LC_MESSAGES/libc.mo", O_RDONLY) = -1 ENOENT 0.1086 open("/usr/share/locale/en/LC_MESSAGES/libc.mo", O_RDONLY) = -1 ENOENT 0.1097 write(2, ": No such file or directory", 27) = 27 0.1110 write(2, "\n", 1) = 1 0.1126 _exit(1)
