Incrementing parts of ten digits number by parts
I have number in file which contains date and serial number:
2013101000.
The last two digits are serial number (00). So maximum of serial number is 100.
After reaching 100 it becomes 00 with incrementing 10 which is day with max 31.
after reaching 31 it becomes 00 and increments 10 which is month with maximum 12.
so basically when I run code it rewrites 10 digits with above conditions... My problem is that I dont know how to separate these 4 numbers. If I have "." or smth like that among them then it would be easier but here I have no idea.....
So example:
cat file
2013113098
sh my_code
cat file
2013113099
sh my_code
cat file
2013113100
sh my_code
cat file
2013113101
then I sh my_code 100 times
cat file
2013120100

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.
