So I have to go to all my shell scripts (some 1000 lines) and have to find out
which parameters are filenames and which ones not. This will take some weeks.
Is there no global flag to control this?
I can not understand why this feature has been dropped. In an windows
environment the new behaviour is very confusing. Here an example how sh.exe
behaves:
C:\sw\bin>mount
C:/unix/bin on /usr/bin type ntfs (binary,auto)
C:/unix/lib on /usr/lib type ntfs (binary,auto)
C:/unix on / type ntfs (binary,auto)
C: on /c type ntfs (text,posix=0,user,noumount,auto)
D: on /d type ntfs (text,posix=0,user,noumount,auto)
S: on /s type ntfs (text,posix=0,user,noumount,auto)
Z: on /z type ntfs (text,posix=0,user,noumount,auto)
C:\sw\bin>sh twg.sh
ok
C:\sw\bin>sh ./twg.sh
ok
C:\sw\bin>sh .\twg.sh
.\twg.sh: line 2: syntax error near unexpected token `$'in\r''
'\twg.sh: line 2: ` case "$funk" in
C:\sw\bin>sh c:\sw\bin\twg.sh
c:\sw\bin\twg.sh: line 2: syntax error near unexpected token `$'in\r''
':\sw\bin\twg.sh: line 2: ` case "$funk" in
C:\sw\bin>
I know "d2u c:\sw\bin\twg.sh" will solve this particular problem but this will
not solve the problems with all the windows files twg.sh reads and writes.
I understand that it can be helpful to make it dependent from the filesystem
but if you use cygwin as an helpful tool in an pure windows environment it's
now confusing and error-prone.
In the past I didn't have to pay attention to line endings. All programs
(windows and cygwin) used CR LF. But now I have to look at each called program
do find out wich line-endings are written.
I think it's hard to understand that the same input gives different results
depending on filenames. You can see a lot of posts here which are about this
problem.
So is there a chance to get back the global setting of textmode, or is there a
way to get textmode without changing all the scripts?
