Hi,
I'm using the following to insert lines into file:
sed ${rowNr}i'\
first row\
second row\
third row\
' file.txt
How can I add tab in front of each added line? "\t" or actual TAB does not seem to work?
Thanks! (2 Replies)
I try to remove empty lines from file and use next:
> cat fl.dat|grep -v '^*$'
or
cat fl.dat|sed '/^*$/d'
'grep' does not removes lines with tabs, 'sed' - lines with <tab> and with <spc>
Why it could be?
Is there any option/env-var should I check?
Thank you

HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted
by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.
SEE ALSO shtool(1), sed(1).
