我想知道有没有办法可以进入

./myscript.sh FILENAME

，文件将链接到

for a in $(cat FILENAME) ; do
done

Answer 1

$ cat > myscript.sh                        # create myscript.sh
for i in "$(cat $1)" ; do echo "$i" ; done # in the end CTRL-d
$ cat > babynames                          # create babynames
primo
secundo                                    # in the end CTRL-d
$ bash myscript.sh babynames               # execute the script with babynames as parameter
primo
secundo

Answer 2

使用以下命令调用脚本：

./myscript.sh babynames 

您可以使用read处理文件的每一行：

while read -r line; do
  echo "$line"
done < "$1"
