I made following scripts but when second time execute this query it copying the new file and in last shows such error "7.log.gz already exists; do you wish to overwrite (y or n)? n" what changes to be done in script that it copies only new file after it exits from loop

Code:

#!/bin/bash

awk '{ a[NR]=$0 } END { for(i=NR; i; --i) print a[i] } ' /home/bin/FILE1 > /home/bin/FILE2 // this command will reverse the order latest first
sleep 1
echo "Today is $(date)"
echo "--------------------"

for i in `cat /home/bin/FILE2`;
do
  if [ ! -f /home/xyz/$i ];
  then cp -r  /home/bin/$i /home/xyz/$i ;
    gzip -9  /home/xyz/$i
    echo "Copying binlogs : $i"
  else
    exit 0
  fi  ;
done
exit 0

Incremental numbering?

Would it be possible for a script to duplicate a file and incrementally number it? File in: XXX_007_0580_xxxx_v0016.aep File out: XXX_007_0580_xxxx_v0017.aep If someone knows of a way I'd love to see it. Thanks!

gzexe

GZEXE(1)						      General Commands Manual							  GZEXE(1)

NAME

       gzexe - compress executable files in place

SYNOPSIS

       gzexe [ name ...  ]

DESCRIPTION

       The  gzexe  utility  allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a
       penalty in performance).  For example if you execute ``gzexe /bin/cat'' it will create the following two files:
	   -r-xr-xr-x  1 root  bin   9644 Feb 11 11:16 /bin/cat
	   -r-xr-xr-x  1 bin   bin  24576 Nov 23 13:21 /bin/cat~
       /bin/cat~ is the original file and /bin/cat is the self-uncompressing executable file.  You can remove /bin/cat~ once  you  are	sure  that
       /bin/cat works properly.

       This utility is most useful on systems with very small disks.

OPTIONS

       -d     Decompress the given executables instead of compressing them.

SEE ALSO

       gzip(1), gznew(1), gzmore(1), gzcmp(1), gzforce(1)

CAVEATS

       The  compressed	executable  is a shell script. This may create some security holes. In particular, the compressed executable relies on the
       PATH environment variable to find gzip and some other utilities (tail, chmod, ln, sleep).

BUGS

       gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually  in  some  cases,
       using chmod or chown.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +--------------------+-----------------+
       |  ATTRIBUTE TYPE    | ATTRIBUTE VALUE |
       +--------------------+-----------------+
       |Availability	    | SUNWgzip	      |
       +--------------------+-----------------+
       |Interface Stability | External	      |
       +--------------------+-----------------+
NOTES

       Source for gzip is available in the SUNWgzipS package.
