Remove tab character from file
I am trying to remove the tab character from a file, which occurs on two places in every line. So far I have tried the following and most are from threads in this forum:
Code:
sed -i '' -e 's/	/ /' file.dat
sed -i '' -e 's/[ \t]*/ /' file.dat
sed -i '' -e 's/\t*/ /g' file.dat
sed -i '' -e 's/[ \t]*//g' file.dat
tr "\011" " " file.dat
perl -i -pe 's/[ \t]+//' file.dat

I am using csh, so perhaps that is one of the reasons why none of these commands work. Is there a different command I should try?
