I'm trying to move files from one location to another on the remote server using sftp below:

for i in a b c d
do
sftp $REMUSR <<EOM>>$OUT 2>&1
rename $SOURDIR/sample_${i}_[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9].gz $REMDIR
quit
EOM
:
:
done

But I get the message:

Couldn't rename file "/source/sample_a_[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9].gz" to "/destin/": No such file or directory

Though this file exists under the /source directory which I've verified:

$ ls -l sample_a_[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9].gz
-rw-r--r--  1 prd admin 112 May 23 09:16 sample_a_20140330.gz

FTP's rename command doesn't compute regular expressions. It interprets the regex as filename that it not present on the system. You are using sftp. Another approach is to use ssh:

for i in a b c d
do
  ssh $user@$host "mv $SOURDIR/sample_a_[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9].gz $REMDIR"
done
  • but @chaos, in one of my earlier snippets:for i in a b c d do sftp $REMUSR <<EOM>>$OUT 2>&1 put $LOCAL_DIR/sample_a_[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9].gz $REMOTE_DIR quit EOM worked and it placed the sample_a_20140330.gz file on the remote server. Does this mean put computes reg exp but rename does not? Am slightly confused here – user68112 May 23 '14 at 6:33
  • Yes, rename just accepts explicit filenames. A regex or a wildcard could match multiple files. put accepts globs. See the manpage of sftp: put: local-path may contain glob(3) characters and may match multiple files. – chaos May 23 '14 at 6:52
  • If I'm sure of having the files in the required format in the $SOURDIR on the server, is there a way to just move all of them to $REMDIR by giving something like rename $SOURDIR/* $REMDIR? Again, am not sure if rename recognises * here, because it didn't work when I tried:-( – user68112 May 23 '14 at 7:37
  • No, rename does not recognise regexes or globs or wildcarts (*, ?), just simple filenames. – chaos May 23 '14 at 8:16
  • Am trying something like this: for i in a b c d do fname=ls sample_${i}_[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9].gz sftp $REMUSR <<EOM>>$OUT 2>&1 rename $SOURDIR/$fname $REMDIR quit EOM : : done ......but no luck – user68112 May 23 '14 at 8:28
