I am trying to use a makefile to sync some of my directories that are on my pc with my thumb drive. For this purpose, I am using multiple commands in a single target.
The makefile looks somewhat like this
pend:
rsync -avhzPu /foo/ /bar/
rsync -avhzPu /bob/ /alice/
But, every time I am doing make -f .sync pend only the first command runs and gives some output along with some error
sent 45.78K bytes received 3.32K bytes 98.20K bytes/sec
total size is 4.42G speedup is 89,981.37
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1196) [sender=3.1.2]
.sync:14: recipe for target 'pend' failed
make: *** [pend] Error 23
But when I am running the commands separately it works. I am not sure what wrong I am doing here.
From the output...
sent 45.78K bytes received 3.32K bytes 98.20K bytes/sec
total size is 4.42G speedup is 89,981.37
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1196) [sender=3.1.2]
.sync:14: recipe for target 'pend' failed
make: *** [pend] Error 23
...the first rsync is failing. If it ends with a non-zero exit code then make will simply bail at that point. If you want make to continue with further commands in the rule then you can explicitly request that it should ignore non-zero exit codes by prefixing a command with a -...
pend:
-rsync -avhzPu /foo/ /bar/
-rsync -avhzPu /bob/ /alice/
This assumes, of course, that simply continuing with the commands is the desired behaviour. Otherwise you need to think more carefully about how to proceed.

Anyone have a clean process for converting samples on macOS to FlameGraphs?
After a bit of fiddling I thought I could perhaps use a tool such as flamegraph-sample, but it seems to give me some trouble and so I thought perhaps there may be other more up-to-date options that I'm missing insomuch that this tool gives an error:
$ sudo sample PID -file ~/tmp/sample.txt -fullPaths 1
Sampling process 198 for 1 second with 1 millisecond of run time between samples
Sampling completed, processing symbols...

I'm using rsync to backup some data from a remote host.
this is how I'm using the rsync cmd:
rsync --dry-run -avhi -e ssh --include-from=/home/rsync_list/test.txt root#10.10.4.61:/ /mnt/BACKUP/my_BACKUP/
this is the file /home/rsync_list/test.txt
+ /usr/acs/conf/**
+ /usr/acs/bin/**
+ /raid0/opmdps/TEMP_folder/**
- *
I want to copy only the listed folders excluding the remaining files.
I always get
receiving file list ... done
sent 103 bytes received 48 bytes 302.00 bytes/sec
total size is 0 speedup is 0.00 (DRY RUN)
Could you tell me what I'm doing wrong? How should I write the rsync command if I would like to sync, for example, only /raid0/opmdps/TEMP_folder/ without its subfolders?
I wonder if you really only tried with the command you posted?
Not only you are using "--dry-run" option, even the output indicates this:
total size is 0 speedup is 0.00 (DRY RUN)
Please consult the manpage:
-n, --dry-run perform a trial run with no changes made
https://linux.die.net/man/1/rsync
May I suggest you give it a run without --dry-run?
I've created a simple go script: https://gist.github.com/kbl/86ed3b2112eb80522949f0ce574a04e3
It's fetching some xml from the internet and then starts X goroutines. The X depends on file content. In my case it was 1700 goroutines.
My first execution finished with:
$ go run mathandel1.go
2018/01/27 14:19:37 Get https://www.boardgamegeek.com/xmlapi/boardgame/162152?pricehistory=1&stats=1: dial tcp 72.233.16.130:443: socket: too many open files

exit status 1
I've tried to increase ulimit to 2048.
Now I'm getting different error, script is the same thou:
$ go build mathandel1.go
# command-line-arguments
/usr/local/go/pkg/tool/linux_amd64/link: flushing $WORK/command-line-arguments/_obj/exe/a.out: write $WORK/command-line-arguments/_obj/exe/a.out: file too large
What is causing that error? How can I fix that?
You ran ulimit 2048 which changed the maximum file size.
From man bash(1), ulimit section:
If no option is given, then -f is assumed.
This means that you now set the maximum file size to 2048 bytes, that's probably not enough for.... anything.
I'm guessing you meant to change the limit for number of open file descriptors. For this, you want to run:
ulimit -n 2048
As for the original error (before changing the maximum file size), you're launching 1700 goroutines, each performing a http get. Each creates a connection, using a tcp socket. These are covered by the open file descriptor limit.
Instead, you should be limiting the number of concurrent downloads. This can be done with a simple worker pool pattern.
I have used cocoa pod and try to archive. After that, I got this error.
I looked solution from here but it doesn't work too. How shall I do?

I have a script that takes in a unique location number from a file. These are formatted like this 7325-05, 5269-09 and 7479-14, for example. The first four numbers are what the folder is called and the second number is the first two characters of the filename unique within each folder.
So I wrote this script to use locate and find to get the full path of the folder and then use a wildcard to download the specific file using rsync. Here's the script that I have right now:
#!/bin/bash
#IFS='
#'
oIFS=$IFS
IFS=$'\n'
while read line;
do
name=$line;
folder=${line:0:4}
track=${line: -2}
folderlocation="$(locate -r '/'$folder'$')"
filelocation="$(find "$folderlocation" -type f -name "$track*")"
rsync -vazhn --progress "$filelocation" /cygdrive/c/
# mkdir /cygdrive/c/test/"$folder"
# cp -rvi "$filelocation" /cygdrive/c/test/"$folder"
echo "";
done < $1
The code using cp that is commented out works just fine. I would just really prefer to use rsync, mainly due to better feedback and more accurate progress reporting, as far as I can tell.
Using the code as pasted above (with rsync) throws this error:
./filelocator classic-locations.txt

As you can see, my home folder (where I issue the command) is suddenly included in the script, leading me to believe that a variable or wildcard is being expanded in the local shell, but no amount of escape characters seem to accomplish what I want with rsync.
