Subject: list files ignoring the case option
Sorry if this is a question more on regular expressions. I am dealing
with several files which have been badly named. For example the files
are given either the extensions txt, TXT or Txt. I wish to select all
those files ending with 'txt' ignoring case.
Here is how I would do it in bash (Redhat FC2) :
touch a1.txt a2.TXT a3.Txt txt.control TXT.control
ls -1 | grep -i "txt$"
Here is how I am currently doing it in R
a <- list.files(all.files=T)
grep( "txt$", a, ignore.case=T, value=T )
Is it possible for me to modify the following line to include ignore
case option ?
a <- list.files( pattern="txt$" )
Thank you.
Regards, Adai
