Refactored among all files that mentioned it.
DANGER WILL ROBINSON! REVIEW CAREFULLY! Here are two major
decisions I made:
1) Look at the text for podman-run, in particular the "" text.
It currently says "will use the default". As best I can
tell this is not true, so I changed it to "will disable"
which matches all the other commands.
2) The "containers.conf" text, I decided, applies to all
commands, not just podman-run (it was only present in
podman-run). If this is not the case, please yell.
Other changes are cosmetic formatting stuff, asterisks end newlines.
Hard to review with hack/markdown-preprocess-review, because all
the text is one horrible long line instead of 80-char breaks.

## NAME
|
|
podman\-exec - Execute a command in a running container
|
|
|
|
## SYNOPSIS
|
|
**podman exec** [*options*] *container* [*command* [*arg* ...]]
|
|
|
|
**podman container exec** [*options*] *container* [*command* [*arg* ...]]
|
|
|
|
## DESCRIPTION
|
|
**podman exec** executes a command in a running container.
|
|
|
|
## OPTIONS
|
|
|
|
#### **--detach**, **-d**
|
|
|
|
Start the exec session, but do not attach to it. The command will run in the background and the exec session will be automatically removed when it completes. The **podman exec** command will print the ID of the exec session and exit immediately after it starts.

|
|
|
|
#### **--latest**, **-l**
|
|
|
|
Instead of providing the container name or ID, use the last created container. If you use methods other than Podman
|
|
to run containers such as CRI-O, the last started container could be from either of those methods. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines)

## Exit Status
|
|
|
|
The exit code from `podman exec` gives information about why the command within the container failed to run or why it exited. When `podman exec` exits with a
|
|
non-zero code, the exit codes follow the `chroot` standard, see below:
|
|
|
|
**125** The error is with Podman itself
|
|
|
|
$ podman exec --foo ctrID /bin/sh; echo $?
|
|
Error: unknown flag: --foo
|
|
125
|
|
|
|
**126** The _contained command_ cannot be invoked
|
|
|
|
$ podman exec ctrID /etc; echo $?
|
|
Error: container_linux.go:346: starting container process caused "exec: \"/etc\": permission denied": OCI runtime error
|
|
126
|
|
|
|
**127** The _contained command_ cannot be found
|
|
|
|
$ podman exec ctrID foo; echo $?
|
|
Error: container_linux.go:346: starting container process caused "exec: \"foo\": executable file not found in $PATH": OCI runtime error
|
|
127
|
|
|
|
**Exit code** The _contained command_ exit code
|
|
|
|
$ podman exec ctrID /bin/sh -c 'exit 3'; echo $?
|
|
3
|
|
|
|
## EXAMPLES
