Hi

Assuming the character to be added is "x" :

awk '{$0=substr($0,1,length($0)-1)"x"substr($0,length($0))}1' /input/file

[gray]# or ( gawk only )[/gray]

awk '{print gensub(/(.)$/,"x\\1","")}' /input/file

[gray]# or[/gray]

sed 's/\(.\)$/x\1/' /input/file

To add an X before the last char of every line:

sed 's/.$/X&/' </path/to/input >/path/to/output

HTH,

Hi

Of course, you are right ! That [tt]&[/tt] works in regular [tt]awk[/tt] implementations too, so can be used in [tt]sub()[/tt].

Thank you, p5wizard.
