bash - Command line commands in a shell script

Question

I have a command that I use in the command line to replace certain lower case characters with upper case, which works fine:

cat file | sed -e 's/^ g/G /;s/^ h/H /;s/^ n/N /;s/^ b/B /' > newfile

Is there a way I can write this into a shell script and call

bash uppercase.sh file

instead of copy and pasting into the command line every time?

Currently when I copy and paste the command into a shell script like:

#!/bin/bash
sed -e 's/^ g/G /;s/^ h/H /;s/^ n/N /;s/^ b/B /'

The terminal becomes unresponsive

尝试将 '$1' 附加到脚本中的 sed 命令，如下所示：

#!/bin/bash
sed -e 's/^ g/G /;s/^ h/H /;s/^ n/N /;s/^ b/B /' $1

然后，像这样运行它：

bash uppercase.sh file
