tr to remove " from a file

ryedunn · 10-26-2006, 11:10 AM

Im trying to use tr to remove all " from a file and output to a new file. Ive tried the literal, wrapping in single ' etc.. its not as easy as I thought it would be.

sed 's/"//g' document1.txt > document2.txt outputs to the screen correctly but tells me it cant find document2.

ok I found that
perl -i.bak -pe 's/"//g' document1.txt
works but that really doesnt teach me why it didnt work before.

You need to escape the double quotes, so for your sed statement you would have had to do this:

sed 's/\"//g' document1.txt > document2.txt

instead of

sed 's/"//g' document1.txt > document2.txt

Code:

ada@barnabas:~/tmp> cat document1.txt
john 10
"mary 20"
rick -
jack 30
ada@barnabas:~/tmp> sed 's/"//g' document1.txt > document2.txt
ada@barnabas:~/tmp> cat document2.txt
john 10
mary 20
rick -
jack 30

This works fine here. Is it possible that you forgot the ">" ?
