Consider you have out.txt on current dir. ------- >exec 123456789012>out.txt bash: exec: 123456789012: not found ------- exec command prints indicated error for large numbers that is supposed to use as a fd but redirects /proc/$$/fd/1 to out.txt silently. Additionally, ------- >exec 1234567890>out.txt bash: 123456789: Bad file descriptor ------- For large numbers but not that large (I don't inspect the limits!), exec command rejects fd number but silently adds a new fd to current bash process. In every execution of the command, bash adds a new fd to itself again and again. ** Affects: bash (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bash in Ubuntu. https://bugs.launchpad.net/bugs/1952584 Title: bash exec command unwanted behaviour Status in bash package in Ubuntu: New Bug description: (GNU bash 4.3.46) (ubuntu 16.04 LTS) Consider you have out.txt on current dir. ------- >exec 123456789012>out.txt bash: exec: 123456789012: not found ------- exec command prints indicated error for large numbers that is supposed to use as a fd but redirects /proc/$$/fd/1 to out.txt silently.
