LinuxSecurity.com: Multiple vulnerabilities have been identified in git-core, the core of the git distributed revision control system. Improper path length limitations in git's diff and grep functions, in combination with maliciously crafted repositories or changes, could enable a stack buffer overflow and potentially the execution of arbitrary code.
GIT-SH(1)GIT-SH(1)NAME
git-sh -- a git shell
SYNOPSIS
git-sh
DESCRIPTION
git-sh starts an interactive bash(1) session modified for git-heavy workflows. Typical usage is to change into the directory of a git work
tree or bare repository and run the git-sh command to start an interactive shell session.
Top-level command aliases are created for all core git(1) subcommands, git-sh builtin aliases (see BUILTIN ALIASES), and git command
aliases defined in ~/.gitconfig.
BUILTIN ALIASES
git-sh loads a set of standard aliases in addition to all core git commands. The builtin aliases are overridden by aliases defined in the
user or system gitconfig files.
a git add
b git branch
c git checkout
d git diff
f git fetch --prune
k git cherry-pick
l git log --pretty=oneline --abbrev-commit
n git commit --verbose --amend
r git remote
s git commit --dry-run --short
t git diff --cached
The Staging Area
a git add
aa git add --update (mnemonic: "add all")
stage git add
ap git add --patch
p git diff --cached (mnemonic: "patch")
ps git diff --cached --stat (mnemonic: "patch stat")
unstage
git reset HEAD
Commits and Commit History
ci git commit --verbose
ca git commit --verbose --all
amend git commit --verbose --amend
n git commit --verbose --amend
k git cherry-pick
re git rebase --interactive
pop git reset --soft HEAD^
peek git log -p --max-count=1
Fetching and Pulling
f git fetch
pm git pull (mnemonic: "pull merge")
pr git pull --rebase (mnemonic: "pull rebase")
Miscellaneous Commands
d git diff
ds git diff --stat (mnemonic: "diff stat")
hard git reset --hard
soft git reset --soft
scrap git checkout HEAD
CUSTOM ALIASES
Anything defined in the [alias] section of the repository, user, or system git config files are also available as top-level shell commands.
Assuming a ~/.gitconfig that looked like this:
[alias]
ci = commit --verbose
ca = commit -a
d = diff
s = status
thanks = !git-thanks
... you might then have the following shell session:
master!something> echo "stuff" >somefile
master!something*> s
M somefile
master!something*> d
diff --git a/somefile b/somefile
-- a/somefile
++ b/somefile
@@ -0,0 +1 @@
+ stuff
master!something*> ca -m "add stuff"
master!something> thanks HEAD
PROMPT
The default prompt shows the current branch, a bang (!), and then the relative path to the current working directory from the root of the
work tree. If the work tree includes modified files that have not yet been staged, a dirty status indicator (*) is also displayed.
The git-sh prompt includes ANSI colors when the git color.ui option is set and enabled. To enable git-sh's prompt colors explicitly, set
the color.sh config value to auto:
$ git config --global color.sh auto
Customize prompt colors by setting the color.sh.branch, color.sh.workdir, and color.sh.dirty git config values:
$ git config --global color.sh.branch 'yellow reverse'
$ git config --global color.sh.workdir 'blue bold'
$ git config --global color.sh.dirty 'red'
See colors in git for information.
COMPLETION
Bash completion support is automatically enabled for all git built-in commands and also for aliases defined in the user ~/.gitconfig file.
The auto-completion logic is smart enough to know an alias d that expands to git-diff should use the same completion configuration as the
git-diff command.
The completion code is a slightly modified version of the git bash completion script shipped with the core git distribution. The script is
built into thegit-sh executable at compile time and need not be obtained or installed separately.
CUSTOMIZING
Most git-sh behavior can be configured by editing the user or system gitconfig files (~/.gitconfig and /etc/gitconfig) either by hand or
using git-config(1). The [alias] section is used to create basic command aliases.
The /etc/gitshrc and ~/.gitshrc files are sourced (in that order) immediately before the shell becomes interactive.
The ~/.bashrc file is sourced before either /etc/gitshrc or ~/.gitshrc. Any bash customizations defined there and not explicitly overrid-
den by git-sh are also available.
ENVIRONMENT
PS1 Set to the dynamic git-sh prompt. This can be customized in the ~/.gitshrc or /etc/gitshrc files.
GIT_DIR
Explicitly set the path to the git repository instead of assuming the nearest .git path.
GIT_WORK_TREE
Explicitly set the path to the root of the work tree instead of assuming the nearest parent directory with a .git repository.
