Re: [R] rename multiple files by file.rename or other functions

2017-09-28 Thread Jim Lemon 
Hi John,
After a bit of thinking:

# fill in the appropriate path and pattern
filenames<-list.files(path=???,pattern=???)
for(filename in filenames) {
 filefirst<-sapply(strsplit(filename,"[.]"),"[",1)
 # delete all non-digits
 fileno<-gsub("[^[:digit:]]","",filefirst)
 file.rename(filename,paste("01Gen",fileno,".mp3",sep=""))
}

The combination of list.files(), gsub() and file.rename() should to the
trick.

I think you can even do this:

strIn <- sprintf("XYZW%02dGenesis_ABC.mp3", 1:50)
strOut <- sprintf("01Gen%02d.mp3", 1:50)
## perhaps try cbind(strIn,strOut) first
file.rename(strIn, strOut)

Re: [R] rename multiple files by file.rename or other functions

2017-09-28 Thread Eric Berger 
Hi John,
Thanks to Jim for pointing out the file.rename() function. You can try this:

# define the filename templates
strIn  <- "XYZW--Genesis_ABC.mp3"
strOut <- "01Gen--.mp3"

# create the strings "01", "02", ..., "50"
v <- sapply(1:50, function(i) sprintf("%02d",i) )

# perform all the file renames
for ( s in v ) { file.rename(sub("--",s,strIn), sub("--",s,strOut) ) }

HTH,
Eric

Hi John,
Maybe this:

filenames<-c("XYZW01Genesis_ABC.mp3","XYZW02Genesis_ABC.mp3")
for(filename in filenames) {
 filefirst<-sapply(strsplit(filename,"[.]"),"[",1)
 fileno<-sub("_","",gsub("[[:alpha:]]","",filefirst))
 file.rename(filename,paste("01Gen",fileno,".mp3",sep=""))
}

Re: [R] rename multiple files by file.rename or other functions

2017-09-28 Thread Ulrik Stervbo 
Hi John,

I don't know how to do this with R, but on Linux I'd use rename (or maybe
even by hand if it's a one time event). On Windows I believe there is a
tool called Bulk Rename.

[R] rename multiple files by file.rename or other functions

2017-09-28 Thread John 
Hi,

   I have 50 files whose names are

XYZW01Genesis_ABC.mp3
XYZW02Genesis_ABC.mp3
...
XYZW50Genesis_ABC.mp3

   As you can tell, the only difference across the files are 01, 02,
03,50.

   I would like to rename them to
01Gen01.mp3
01Gen02.mp3
...
01Gen50.mp3

  If I store them in one folder and write an R code in that folder, how can
it be done?

   Thanks,

John
