Displaying output and copying to a file - tee command
Displaying program output and copying to a file (tee command)
tee command, used with a pipe, reads standard input, then writes the output of a program to standard output and simultaneously copies it into the specified file or files. Use the tee command to view your output immediately and at the same time, store it for future use.
For example, type the following:
db2 get dbm cfg | tee dbm.outThis displays the standard output of the "db2 get dbm cfg" command on the display device, and at the same time, saves a copy of it in the dbm.out file. If the dbm.out file already exists, it is deleted and replaced unless the noclobber option of the set built-in command is specified.
For example, to view and save the output from
a command to an existing file:
ls -l | tee -a program.lsThis displays the standard output of ls -l at the display device and at the same time appends a copy of it to the end of the program.ls file.
The
system displays information similar to the following, and the program.ls file
contains the same information:
