Relax initial regexp to match more instances, but add a filter to avoid some invalid conversions. Run this: git grep -l "\`[^']*'" tests | xargs perl -pi -e '$q=q"'\''";' \ -e '$q="$q\\$q$q"; /(= ?\`|\`expr|\`echo|\Q$q\E)/ and next;' \ -e ' s/\`([^'\''"]*?'\'')/'\''$1/g' The last disjunct in the above (...) filter is to exempt any line that contains this string: '\'' With quoting like that, converting a ` to ' is likely to cause trouble, so we'll handle those manually. Here are three examples where the exemption is required: *': `link-to-dir/'\'': hard link not allowed for directory'*) ;; printf 'creating file `%s'\''\n' $f 'mv: inter-device move failed: `%s'\'' to `%s'\'';'\
