Copy files from multiple directories into one directory without overwriting them
I have several directories and all those directories have .dat files in them. I want to copy all those .dat files to one directory say "collected_directory"
The problem is I don't want to overwrite files. So, if two file names match, I don't want the old file to be overwritten with a new one.
I know how to copy files from multiple directories to one directory:
But how to handle the case where no overwrite occurs rather the same file names get a new name like abc_1.dat if abc.dat already exists in "collected_directory"?
I have a report file that is generated every day by a scheduled process.
Each day the file is written to a directory named .../blah_blah/Y07/MM-DD-YY/reportmmddyy.tab
I want to copy all of this reports to a separate directory without having to do it one by one.
However, if I try

I have a lot of binary files I need to copy to a folder. The folder is already filled with files of the same name. Copying on top of the old files takes MUCH longer than if I were to delete the old files then copy the new files to the now-empty folder. This result is specific to one system -... (3 Replies)

trace-cmd-restore
TRACE-CMD-RESTORE(1)TRACE-CMD-RESTORE(1)NAME
trace-cmd-restore - restore a failed trace record
SYNOPSIS
trace-cmd restore [OPTIONS] [command] cpu-file [cpu-file ...]
DESCRIPTION
The trace-cmd(1) restore command will restore a crashed trace-cmd-record(1) file. If for some reason a trace-cmd record fails, it will
leave a the per-cpu data files and not create the final trace.dat file. The trace-cmd restore will append the files to create a working
trace.dat file that can be read with trace-cmd-report(1).
When trace-cmd record runs, it spawns off a process per CPU and writes to a per cpu file usually called trace.dat.cpuX, where X represents
the CPU number that it is tracing. If the -o option was used in the trace-cmd record, then the CPU data files will have that name instead
of the trace.dat name. If a unexpected crash occurs before the tracing is finished, then the per CPU files will still exist but there will
not be any trace.dat file to read from. trace-cmd restore will allow you to create a trace.dat file with the existing data files.
OPTIONS -c
Create a partial trace.dat file from the machine, to be used with a full trace-cmd restore at another time. This option is useful for
embedded devices. If a server contains the cpu files of a crashed trace-cmd record (or trace-cmd listen), trace-cmd restore can be
executed on the embedded device with the -c option to get all the stored information of that embedded device. Then the file created
could be copied to the server to run the trace-cmd restore there with the cpu files.
If *-o* is not specified, then the file created will be called
'trace-partial.dat'. This is because the file is not a full version
of something that trace-cmd-report(1) could use.
-t tracing_dir
Used with -c, it overrides the location to read the events from. By default, tracing information is read from the debugfs/tracing
directory. -t will use that location instead. This can be useful if the trace.dat file to create is from another machine. Just tar
-cvf events.tar debugfs/tracing and copy and untar that file locally, and use that directory instead.
-k kallsyms
Used with -c, it overrides where to read the kallsyms file from. By default, /proc/kallsyms is used. -k will override the file to read
the kallsyms from. This can be useful if the trace.dat file to create is from another machine. Just copy the /proc/kallsyms file
locally, and use -k to point to that file.
-o output'
By default, trace-cmd restore will create a trace.dat file (or trace-partial.dat if -c is specified). You can specify a different file
to write to with the -o option.
-i input
By default, trace-cmd restore will read the information of the current system to create the initial data stored in the trace.dat file.
If the crash was on another machine, then that machine should have the trace-cmd restore run with the -c option to create the trace.dat
partial file. Then that file can be copied to the current machine where trace-cmd restore will use -i to load that file instead of
reading from the current system.
EXAMPLES
If a crash happened on another box, you could run:
$ trace-cmd restore -c -o box-partial.dat
Then on the server that has the cpu files:
$ trace-cmd restore -i box-partial.dat trace.dat.cpu0 trace.dat.cpu1
This would create a trace.dat file for the embedded box.
