- sort -f
- uniq -i grep -i
- find -iname (Like -name, but the match is case insensitive)
find -iregex (Like -regex, but the match is case insensitive)
and many more find -i's. - ls : no case insensitive search possible
- sed -e 's/REGEXP/REPLACE/gI'
Alternative sed -e 's/[a-zA-Z]/REPLACE/g'
ie:
$ echo AbCdefXyZ | sed 's/[c-e]/1/gI'
gives the same result as
$ echo AbCdefXyZ | sed 's/[c-eC-E]/1/g')
But.... The ignorecase indicator. Is mostly case sensitive.
