Details:
Hi,
'\nfoo' is interpreted differently by echo:
| f...@bar % cat Makefile
| default:
| echo '\nfoo'
| echo '\nfoo' > bar
| f...@bar % make
| echo '\nfoo'
| \nfoo
| echo '\nfoo' > bar
| f...@bar % cat bar
|
| foo
| f...@bar % ls -l /bin/sh
| lrwxrwxrwx 1 root root 4 11. Aug 11:51 /bin/sh -> dash
If SHELL is set to '/bin/dash' this changes:
| f...@bar % cat Makefile
| SHELL=/bin/dash
| default:
| echo '\nfoo'
| echo '\nfoo' > bar
| f...@bar % make
| echo '\nfoo'
|
| foo
| echo '\nfoo' > bar
| f...@bar % cat bar
|
| foo
When SHELL is set to '/bin/sh' the strange behavior arises again:
| f...@bar % cat Makefile
| SHELL=/bin/sh
| default:
| echo '\nfoo'
| echo '\nfoo' > bar
| f...@bar % make
| echo '\nfoo'
| \nfoo
| echo '\nfoo' > bar
| f...@bar % cat bar
|
| foo
HTH
| f...@bar % make --version
