Just want to exclude lines with tabs

[xyz2041]

Hi,

I just want to exclude lines that have tabs on them.

I've tried all of these, but none work.

What am I missing?


grep "$(echo -e \\t)" o.csv
grep "$(printf '\t')" o.csv
grep "\t" o.csv > o-out.csv
grep $',' o.csv > o-out.csv
grep $'\t' o.csv > o-out.csv
grep -P "\t" o.csv > o-out.csv
grep -r ',' o.csv
grep -v "[[:tab:]]" o.csv > o-out.csv
grep -v "\t" o.csv > o-out.csv
grep -v "\t" o.csv > o-out.csv
grep -v $"\t" o.csv > o-out.csv
grep -v $'\t' o.csv > o-out.csv
grep -v '[ \t]' o.csv > o-out.csv
grep -v \t o.csv > o-out.csv
grep -v '\t' o.csv > o-out.csv
grep -v -e "\t" o.csv > o-out.csv
grep -v- -e "\t" o.csv > o-out.csv
grep -v -e '\t' o.csv > o-out.csv
grep -w ',' o.csv > o-out.csv
