alignment of variable
Dear Champs,

i have a file let a.txt having value
number text
00 123
012
145 456
...etc

i need number and text column vales should right align ??? how can i achive this ???

NOTE number is of max 3 char and text can take max 7 char...so if any records are less than above lengths then their left side should be *
if any column values are missing then it should be *
e.g
o/p of a.txt should be
number text
*00****123
012*******
145****456

You could use printf and then replace spaces with asterisks.

Code:
awk '{ p=sprintf("%3s%7s", $1, $2); gsub(/ /, "*", p); print p }' a.txt

If your awk doesn't have the gsub function, see if you can find nawk or mawk or gawk or an XPG4 awk on your system.

thanx era....

now i just want to pass these column name i.e. number and text as variable (now max length of number is 10 and of text is 7)
and only header should be right aligned and append into some other file . and no indention of content is require .

Then let me know any suggestions .

e.g bbbbNUMBERbbbTEXT
NOTE: b is the blank space
