Hi,
Try:
from1 <- list.files() ##folder where files are stored
?from1
#[1] "p126r62_5t19880613_nn1.tif.gz" "p126r62_5t19880613_nn2.tif.gz"
#[3] "p200r65_5t19880613_nn1.tif.gz"

to1 <- gsub("^p(\\d+)r(\\d+)\\_.{2}(\\d{8})\\_nn(.*)","LT5\\10\\2\\3XXXX_B\\4",from1)
?file.rename(from1,to1)
#[1] TRUE TRUE TRUE
?list.files()
#[1] "LT512606219880613XXXX_B1.tif.gz" "LT512606219880613XXXX_B2.tif.gz"
#[3] "LT520006519880613XXXX_B1.tif.gz"

Hi guys, 

Thank you for reply 

Actually I have thousands of ?files and I would like to change file name, then I can use it in my software ? 

e.g The original file 
? ? ? p126r62_5t19880613_nn1.tif.gz 

The expected change 
LT512606219880613XXXX_B1.tif.gz 

The every single character in original files has some meaning 
? p126r62_5t19880613_nn1.tif.gz 
p(path)126(path number) r (raw)62(rownumber)_5t(name of instrument)19880613(date)_nn1(band number).tif.gz 
So I would like to replace some part 

p ? ? ? = LT5 
r ? ? ? ?= 0 
_5t ? ?=remove 
_nn ? ?=B 
XXXX=add after date 

I have tried file.rename() function but I was unable to apply this change to all files. 
is it possible to use file.rename function to apply for all file?

I have list of files in folder 

e.g p126r62_5t19880613_nn1.tif.gz 
? ? ?p126r62_5t19880613_nn2.tif.gz 
? ? ?p200r65_5t19880613_nn1.tif.gz 

and I would like to change file name to 
? ? ?LT512606219880613XX_B1.tif.gz 
? ? ?LT512606219880613XX_B2.tif.gz 
? ? ?LT520006519880613XX_B1.tif.gz 

Does any body knows how It can be changed?
