awk or sed to format text file
hi all,

i have a text file which looks like the below
Code:
01 
02 
abc Top 40
music
Kidz Only!
MC 851
MC 852
MC 853
7NOW
Arch_Diac
xyz2
abc
h211
Commacc1
Commacc2
Commacc3
5 max
5 max HD
@MAX
@MAX HD
Action MA
08 
09 
10 
BBC World News 
BET ON

here if anything starting with number and then have character next to it must be converted into character and then number
if its just a number then it must left as it is

eg

"7NOW" must be converted to NOW7 and "5 max" must be converted to "max 5" (max5 doesnt matter)


the output must look like this
Code:
01
02
abc Top 40
music
Kidz Only!
MC 851
MC 852
MC 853
NOW7
Arch_Diac
xyz2
abc
h211
Commacc1
Commacc2
Commacc3
max 5
max HD 5
@MAX
@MAX HD
Action MA

Hi

Try this perl snippet:
Code:
[root@gpr ~]# cat f1.pl
#!/usr/bin/perl -n

chop;
if (/^(\d+) (\D+)$/){
  print $2, " ", $1, "\n";
}elsif (/^(\d+)([a-zA-Z]+)$/){
        print $2,$1,"\n";
}else{
       print $_, "\n";;
}
[root@gpr ~]#

Run: (where a is the input file)
Code:
[root@gpr ~]# ./f1.pl a
01
