Hi,
For the 2nd eval in main1.sh, the LINENO is not at the actual line
number of the eval command. This behavior is counter-intuitive. Would
it be better to make it show the line number of the 2nd eval? Thanks.
$ cat script.sh
#!/usr/bin/env bash
# vim: set noexpandtab tabstop=2:
echo "$LINENO"
$ cat main1.sh
#!/usr/bin/env bash
# vim: set noexpandtab tabstop=2:
eval '#!/usr/bin/env bash
# vim: set noexpandtab tabstop=2:
echo "$LINENO"
'
eval "$(< ./script.sh)"
echo "$LINENO"
$ ./main1.sh
