Replace a string in quote to uppercase
Hi,
I need to find all strings in single quote and change the case of the string to UPPER.

Example:

Input:
xyz abc ccc 'zxxx7U'
dfsdf sdfdd aaa 'oR77' and 'or88'

Output:
xyz abc ccc 'ZXXX7U'
dfsdf sdfdd aaa 'OR77' and 'OR88'

Appreciate your help!!

Thanks
Selva

Code:
sed "s/'\(.*\)'/'\U\1'/" file_name


HTH,

I think a lazy match should be used (this works in GNU sed on matches on the same line)
Code:
sed "s/'\([^']*\)'/'\U\1'/g"

Code:
awk '{for (i=1;i<=NF;i++) {if ($i~/^'\''.*'\''$/) $i=toupper($i)}}1' urfile

interesting, one single quota need be used as '\'' in awk (three single quotas)

The \U does not work, other parts work.

\U works only in VI editor, but not while part of a script.

The solution of rdcwayx should work.

Another one:
Code:
awk -F"'" '{for(i=2;i<NF;i+=2){$i=toupper($i)}}1' OFS="'" file
