Man 1 utime4/11/2023 ![]() Will exit with one of the following values: 1-125Īn error occurred in the time utility. If utility is invoked, the exit status of time will be the exit status of utility otherwise, the time utility Variables that affect the execution of time: LC_CTYPE, LC_MESSAGES, See environ(5) for descriptions of the following environment ![]() See csh(1) for an explanation of the formatĮxample% /usr/bin/time find / -name csh.1 -print The following two examples show the differences between the csh version of time and the version in /usr/bin/time. This can be done by placing pipelines and command lists in a single file this file can then be invokedĪs a utility, and the time applies to everything in the file.Īlternatively, the following command can be used to apply time to a complex command: ![]() It is frequently desirable to apply time to pipelines or lists of commands. The value 126 was chosen in a similar manner to indicate that the utility could The time utility returns exit status 127 if an error occurs so that applications can distinguish "failure to find a utility" from "invoked utilityĮxited with an error indication." The value 127 was chosen because it is not commonly used for other meanings most utilities use small values for "normal error conditions"Īnd the values above 128 can be confused with termination due to receipt of a signal. argumentĪny string to be supplied as an argument when invoking utility. The name of the utility that is to be invoked. The following operands are supported: utility Write the timing output to standard error in the following format: On the left are unspecified those on the right report on utilities a and c, respectively. When time is used as part of a pipeline, the times reported are unspecified, except when it is the sole command within a grouping command in that pipeline. The System CPU time, equivalent to the sum of the tms_stime and tms_cstime fields returned by the times()įunction for the process in which utility is executed. The User CPU time, equivalent to the sum of the tms_utime and tms_cutime fields returned by the times(2) function for the process in which utility is executed. The elapsed (real) time between invocation of utility and its termination. The message includes the following information: The time utility invokes utility operand with argument, and writes a message to standard error that lists timing statisticsįor utility.
