我在网上找到了下面的函数(感谢编写它的人)。问题似乎更多是包装输出。我喜欢逐页查看输出的选项,但不喜欢包装。我怎样才能更改为不换行,但允许像 less 或 more 命令一样滚动输出?
# Find a pattern in a set of files and highlight them:
#+ (needs a recent version of egrep).
function fstr()
{
OPTIND=1
local mycase=""
local usage="fstr: find string in files.
Usage: fstr [-i] \"pattern\" [\"filename pattern\"] "
while getopts :it opt
do
case "$opt" in
i) mycase="-i " ;;
*) echo "$usage"; return ;;
esac
done
shift $(( $OPTIND - 1 ))
if [ "$#" -lt 1 ]; then
echo "$usage"
return;
fi
find . -type f -name "${2:-*}" -print0 | \
xargs -0 egrep --color=always -sn ${case} "$1" 2>&- | more
}
