Package: bash
Version: 3.2-4
Severity: normal
I'm not really sure whose fault this is, because the circumstances where
the problem manifests itself are so specific. This is the shortest
example I could find to reproduce the problem:
--- clip ---
while read line; do ssh somemachine echo "'$line'" | tr a a; done < somefile
--- clip ---
This command will _not_ echo all lines in koe.c, and the number of lines
it manages to echo seems to vary indeterministically:
--- clip ---
[ate...@aulis ~]$ while read rivi; do ssh oiva echo "'$rivi'" | tr a a; done <
tmp/koe.c
void f( char ** const w ) {};
int main( int argc, char * argv[] ) {
char foo[10];
char * p = &foo[0];
[ate...@aulis ~]$ while read rivi; do ssh oiva echo "'$rivi'" | tr a a; done <
tmp/koe.c
void f( char ** const w ) {};
[ate...@aulis ~]$
--- clip ---
All of these ingredients seem to be necessary to trigger the problem:
while loop with read, making a pipe within the while loop, and using ssh
in the pipe. That is, if I replace "ssh oiva echo" with just "echo",
all lines get echoed; if I leave off "| tr a a", all lines get echoed.
I couldn't find any other program except ssh that I could get to
reproduce the problem. This seems very peculiar.
