This is what I have got so far.
Code:
abc.txt:
NAME1 NAME2 ADDRESS TEL
A B ADD 1234
 
awk -F"\t" '
NR==1{
for(i=1;i<=NF;i++)
if($i~/ID/)f[n]=i
n++
for(i=1;i<=NF;i++)
if($i~/NAME1/)f[n]=i
n++
for(i=1;i<=NF;i++)
if($i~/NAME2/)f[n]=i
n++
for(i=1;i<=NF;i++)
if($i~/EMAIL/)f[n]=i
n++
for(i=1;i<=NF;i++)
if($i~/ADDRESS/)f[n]=i
n++
for(i=1;i<=NF;i++)
if($i~/TEL/)f[n]=i
n++
}
{
if (NR==1)
print "ID NAME1 NAME2 EMAIL ADDRESS TEL"; 
}
{
if (NR > 1) {
for(i=0;i<n;i++)
printf"%s%s",i?" ":"",$f[i];
print""
}
}
' abc.txt

But I keep getting the error "Field is not correct"
I think the error is due to the ID AND EMAIL column not found (by searching for the column name) in abc.txt, hence f[n] evaluates to blank. When the code tries to do printf with $<blank>, it gives this error.

I am almost there, just need a tip how i can handle printf $<blank> so that it prints a blank column rather than errored out.

As i said, i am very new to unix scripting Smilie

mdbFontSize(5)							 The m17n Library						    mdbFontSize(5)

NAME
mdbFontSize - Font Size DESCRIPTION
In some case, a font contains incorrect information about its size (typically in the case of a hacked TrueType font), which results in a bad text layout when such a font is used in combination with the other fonts. To overcome this problem, the m17n library loads information about font-size adjustment from the m17n database by the tags <font, resize>. The data is loaded as a plist of this format. FONT-SIZE-ADJUSTMENT ::= PER-FONT * PER-FONT ::= '(' FONT-SPEC ADJUST-RATIO ')' FONT-SPEC ::= '(' [ FOUNDRY FAMILY [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]] REGISTRY ')' ADJUST-RATIO ::= INTEGER FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font. See m17nFont for the meaning of each property. ADJUST-RATIO is an integer number specifying by percentage how much the font-size must be adjusted. For instance, this PER-FONT: ((devanagari-cdac) 150) instructs the font handler of the m17n library to open a font of 1.5 times bigger than a requested size on opening a font whose registry is 'devanagari-cdac'.
