Top Forums Shell Programming and Scripting Large Variable content size caveats? Post 303031979 by Corona688 on Friday 8th of March 2019 10:58:00 AM

Main caveat, it's almost almost always a dumb idea. Ad-hoc data, "dump-and-fix-later", is the modern UUOC, wasteful and pointless. If you know what you actually want, you can either deal with it in a structured way or avoid storing it entirely.

Another caveat, most shells don't let you keep binary data in variables. Mass dumping unchecked data into variables can occasionally surprise you.

GIT-CHECK-ATTR(1)						    Git Manual							 GIT-CHECK-ATTR(1)

NAME
git-check-attr - Display gitattributes information SYNOPSIS
git check-attr attr... [--] pathname... git check-attr --stdin [-z] attr... < <list-of-paths> DESCRIPTION
For every pathname, this command will list if each attribute is unspecified, set, or unset as a gitattribute on that pathname. OPTIONS
--stdin Read file names from stdin instead of from the command-line. -z Only meaningful with --stdin; paths are separated with a NUL character instead of a linefeed character. -- Interpret all preceding arguments as attributes and all following arguments as path names. If not supplied, only the first argument will be treated as an attribute. OUTPUT
The output is of the form: <path> COLON SP <attribute> COLON SP <info> LF <path> is the path of a file being queried, <attribute> is an attribute being queried and <info> can be either: unspecified when the attribute is not defined for the path. unset when the attribute is defined as false. set when the attribute is defined as true. <value> when a value has been assigned to the attribute. EXAMPLES
In the examples, the following .gitattributes file is used: .ft C *.java diff=java -crlf myAttr NoMyAttr.java !myAttr README caveat=unspecified .ft o Listing a single attribute: .ft C $ git check-attr diff org/example/MyClass.java org/example/MyClass.java: diff: java .ft o Listing multiple attributes for a file: .ft C $ git check-attr crlf diff myAttr -- org/example/MyClass.java org/example/MyClass.java: crlf: unset org/example/MyClass.java: diff: java org/example/MyClass.java: myAttr: set .ft o Listing an attribute for multiple files: .ft C $ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java org/example/MyClass.java: myAttr: set org/example/NoMyAttr.java: myAttr: unspecified .ft o Not all values are equally unambiguous: .ft C $ git check-attr caveat README README: caveat: unspecified .ft SEE ALSO
