I have a flat file where I have multiple occurrences of strings that contains single quote, e.g.
sed -e 's/"'"/ /g' myfile.txt
sed -e 's/"'"/" "/g' myfile.txt
Try to keep sed commands simple as much as possible or else you'll get confused of what you'd written after reading it later.
#!/bin/bash sed "s/'/ /g" myfile.txt
