Splitting file

Hello
I have one file which is around 20MB.
File name = ABCD_XYZ_20130302223203.xml

wanted to split up into four files of each size of 5 MB.

Requirement is that to write script which should do as : first three file should be of size 5 MB each, the fourth one content should be in the last file whatever it may be less or more than 5 MB.

*Splitted file name should be same as the original with appeneding 1,2,3.

I have used
split -b 5M ABCD_XYZ_20130302223203.xml
but its splitting in file name as
xaa
xab
xac
xad

Appreciate your help in this.

so read the man page of split:

Code:

split [OPTION]... [INPUT [PREFIX]]



Output  fixed-size  pieces  of  INPUT to PREFIXaa, PREFIXab, ...;



 -b, --bytes=SIZE

              put SIZE bytes per output file



  -d, --numeric-suffixes

              use numeric suffixes instead of alphabetic

I think you only need to find PREFIX and suffix properly

Thanks for your advice

My Box is AIX and I dont a have -d option for numeric suffix.

I am using

filename="ABCD_XYZ_20130302223203.xml"
split -b 5M -a2 $filename "${filename}_"

got some output like
ABCD_XYZ_20130302223203.xml_aa
ABCD_XYZ_20130302223203.xml_ab

But the expected one as...
ABCD_XYZ_20130302223203_1.xml
ABCD_XYZ_20130302223203_2.xml

OR
Same name for all splitted files as original like
ABCD_XYZ_20130302223203.xml
ABCD_XYZ_20130302223203.xml
ABCD_XYZ_20130302223203.xml
ABCD_XYZ_20130302223203.xml

Appreciate your input.

[aix sux]
this could be messy but:

Code:

i=0;for file in x*

do

 i=`expr $i + 1`

 mv $file ABCD_XYZ_20130302223203_$i.xml

done
