How to conveniently specify a long line of command options?

[Vonigol]

Hello!

I am hooking GRUB bootloader's built-in commands. When I use GRUB's "./configure" to rebuild GRUB, I need to specify a lot of options in the command line. This is very inconvenient. Is there any way to type those options in some text file and then use it together with ./configure?

Some examples.

Lets "options.txt" be the file with the command line options that I need to specify. For example, it will contain the following text:

--enable-protector-mode \
--enable-example-kernel \
--disable-reiserfs \
--disable-iso9660 \
--disable-ffs \
"CFLAGS=-g -fno-stack-protector"

I tried the following variants but without success:

1) $ ./configure 'cat options.txt'
2) $ ./configute $(cat options.txt)
3) cat options.txt | ./configure

configure either doesn't understand the backlash ('\') from 'options.txt' or doesn't like CFLAGS. If I copy the text from "options.txt" and then manually insert it immediately after "$ ./configure ", then everything works fine. For example, why doesn't variant number 3) work?

Can anyone help me?

Thanks.

Best regards,

How about using a bash script (.rc)? Clicky

"alias" might also help.

--enable-protector-mode \
--enable-example-kernel \
--disable-reiserfs \
--disable-iso9660 \
--disable-ffs \
"CFLAGS=-g -fno-stack-protector"

you need to space seperate them not newline, 'cat' does not understand \ to mean continue on the line

3) cat options.txt | ./configure

this puts the options on stdin of configure, not the command line

what you should do is space seperate the options ( put them on the same line ) then do

Code: Select all

./configure `cat options.txt`

notice these are ` not '
