Question Redirect the Time result to a test file
I need to store process runtime into a file, currently the command i use was:

time ls >> abc.txt

however, this command store the executed result of ls into the txt file but not the time command result.

Anyone know how to store the "time ls" result? Please advise me! Thanks in advance Smilie

as per man pages time output is printed on stderr.

so this will do

time ls > abc.txt 2>tm.txt

abc.txt - op of ls command
tm.txt - op of time command

try time -p ls 2>abc.txt

If this doesn't work, try with the full path of time command.. it works.

doesn't work, the abc.txt is empty.

what mean by full path of time command? can have example?

have you tried the following

Quote:
time ls > abc.txt 2>tm.txt

abc.txt - op of ls command
tm.txt - op of time command

mistella, to get the path to a command, you can try running 'which <command>'. This will give you the path to the command. Like this:
Code:
# which time
/usr/bin/time

Also, vidhya has asked you to use the full path of the time command because the shell that you are using also has a builtin called time that will be executed instead of the time binary if you just run 'time'.
