My problem is with system2 syntax.
I am trying to rename filenameA to filenameB in linux. but I need to use full qualified paths, and rename does not like this, so I propose to use "mv".
I plan use system2 and "mv" (eventually with map) to march across my list of original filenames and new filenames, but I am doing something wrong with system2 as the following code demonstrates:
- first I show you a single filename,
- then I use file.info() to show that file.info() can find the single file,
- then I show you the system2 "fail"
- then I show the recovered linux command issued by system2 succeeding in the shell.
Suggestions?
here is a single filename
monthlyzipinfo[1] [1] "/home/rob/KRBD_Data/Client_ID/000/raw/monthzips/2015-01/Data_2015-01-07.zip"
here is the result from file.info
file.info(monthlyzipinfo[1])
size isdir mode mtime
/home/rob/KRBD_Data/Client_ID/000/raw/monthzips/2015-01/Data_2015-01-07.zip 3911 FALSE 664 2017-05-17 09:38:18 ctime atime uid gid /home/rob/KRBD_Data/Client_ID/000/raw/monthzips/2015-01/Data_2015-01-07.zip 2017-05-17 11:37:29 2017-05-17 09:27:48 1000 1000 uname grname /home/rob/KRBD_Data/Client_ID/000/raw/monthzips/2015-01/Data_2015-01-07.zip rob rob
but system2 fails
system2(paste("ls -la", monthlyzipinfo[1])) sh: 1: ls -la /home/rob/KRBD_Data/Client_ID/000/raw/monthzips/2015-01/Data_2015-01-07.zip: not found
but if I cut and paste the linux command from system2, that works;
rob@NewMachine:~$ ls -la /home/rob/KRBD_Data/Client_ID/000/raw/monthzips/2015-01/Data_2015-01-07.zip -rw-rw-r-- 1 rob rob 3911 May 17 09:38 /home/rob/KRBD_Data/Client_ID/000/raw/monthzips/2015-01/Data_2015-01-07.zip rob@NewMachine:~$
