Hi,
I have to check whether an argument say $ARGV is not null in an if operator. Please let me know the operator. It would be great if you write a psuedo code.
Thanks in advance

I'm having problems with bash scripts. If a bash script is called with no arguments, I always get "PHIST=!" as the first argument (i.e. this is what $1 equals). Why? Where does this come from, and how can I fix it? Nothing in the bash man pages refer to this mysterious default argument. (2 Replies)

Hi,
I'm trying to make a bash script that if a null value is returned then to output the value 0.
I would like a script to search the 'top' tree and return the CPU value of a process, however if the process is not running for it to return 0 or another identifier.

I pass an argument to bash as run. The first command in green executes as expected, however the second in blue fails as the $run does not expand.

git-sh-setup
GIT-SH-SETUP(1) Git Manual GIT-SH-SETUP(1)NAME
git-sh-setup - Common Git shell script setup code
SYNOPSIS
. "$(git --exec-path)/git-sh-setup"
DESCRIPTION
This is not a command the end user would want to run. Ever. This documentation is meant for people who are studying the Porcelain-ish
scripts and/or are writing new ones.
The git sh-setup scriptlet is designed to be sourced (using .) by other shell scripts to set up some variables pointing at the normal Git
directories and a few helper shell functions.
Before sourcing it, your script should set up a few variables; USAGE (and LONG_USAGE, if any) is used to define message given by usage()
shell function. SUBDIRECTORY_OK can be set if the script can run from a subdirectory of the working tree (some commands do not).
The scriptlet sets GIT_DIR and GIT_OBJECT_DIRECTORY shell variables, but does not export them to the environment.
FUNCTIONS
die
exit after emitting the supplied error message to the standard error stream.
usage
die with the usage message.
set_reflog_action
Set GIT_REFLOG_ACTION environment to a given string (typically the name of the program) unless it is already set. Whenever the script
runs a git command that updates refs, a reflog entry is created using the value of this string to leave the record of what command
updated the ref.
git_editor
runs an editor of user's choice (GIT_EDITOR, core.editor, VISUAL or EDITOR) on a given file, but error out if no editor is specified
and the terminal is dumb.
is_bare_repository
outputs true or false to the standard output stream to indicate if the repository is a bare repository (i.e. without an associated
working tree).
cd_to_toplevel
runs chdir to the toplevel of the working tree.
require_work_tree
checks if the current directory is within the working tree of the repository, and otherwise dies.
require_work_tree_exists
checks if the working tree associated with the repository exists, and otherwise dies. Often done before calling cd_to_toplevel, which
is impossible to do if there is no working tree.
require_clean_work_tree <action> [<hint>]
checks that the working tree and index associated with the repository have no uncommitted changes to tracked files. Otherwise it emits
an error message of the form Cannot <action>: <reason>. <hint>, and dies. Example:
require_clean_work_tree rebase "Please commit or stash them."
get_author_ident_from_commit
outputs code for use with eval to set the GIT_AUTHOR_NAME, GIT_AUTHOR_EMAIL and GIT_AUTHOR_DATE variables for a given commit.
create_virtual_base
modifies the first file so only lines in common with the second file remain. If there is insufficient common material, then the first
file is left empty. The result is suitable as a virtual base input for a 3-way merge.
