This has been done with the following script: find -path ./.git -prune -o -type f -print0 | xargs -0 -r sed -i \ -e 's/u2boot/barebox/g' \ -e 's/U2Boot/barebox/g' \ -e 's/U-boot V2/barebox/g' \ -e 's/u-boot v2/barebox/g' \ -e 's/U-Boot V2/barebox/g' \ -e 's/U-Boot-v2/barebox/g' \ -e 's/U_BOOT/BAREBOX/g' \ -e 's/UBOOT/BAREBOX/g' \ -e 's/uboot/barebox/g' \ -e 's/u-boot/barebox/g' \ -e 's/u_boot/barebox/g' \ -e 's/U-Boot/barebox/g' \ -e 's/U-boot/barebox/g' \ -e 's/U-BOOT/barebox/g' find -path ./.git -prune -o \( -name "*u-boot*" -o -name "*uboot*" -o -name "*u_boot*" \) -print0 | \ xargs -0 -r rename 's/u[-_]?boot/barebox/' It needs some manual fixup following in the next patch Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
