Top Forums Shell Programming and Scripting [BASH] Using a function to write data to a file Post 302411153 by curleb on Wednesday 7th of April 2010 08:54:36 PM

if I might add, both methyl and jlliagre are right-ish on the matter of the syntax...but kshji is most right in suggesting a bum char is gumming up the works...

The "<<- _EOF_" is very much usable (as well as not necessary...), so long as the shell supports it and the whitespace is in fact a space (hex:20). A tab char will not do, and actually causes the function to hang altogether, so an od -c would be most helpful in sorting out the root cause of the failure. Otherwise, manually re-create what you want to happen and then copy/paste it from whatever history file you're logging to...

My .02...

actually, it was jlliagre who'd suggested the octal dump...my bad!

can't leave well-enough alone...

Code:
$ tail -16 file_test.txt

cat <<- _EOF_
blah...[space]
_EOF_

cat <<- _EOF_
blah...[tab]-less
_EOF_

cat <<- _EOF_
blah...[tab]-more
        _EOF_

cat <<- _EOF_
blah...[space]-tab
        _EOF_

$ tail -16 file_test.txt |od -c
0000000  \r  \n   c   a   t       <   <   -       _   E   O   F   _  \r

NAME
git-ls-tree - List the contents of a tree object SYNOPSIS
git ls-tree [-d] [-r] [-t] [-l] [-z] [--name-only] [--name-status] [--full-name] [--full-tree] [--abbrev[=<n>]] <tree-ish> [<path>...] DESCRIPTION
Lists the contents of a given tree object, like what "/bin/ls -a" does in the current working directory. Note that: o the behaviour is slightly different from that of "/bin/ls" in that the <path> denotes just a list of patterns to match, e.g. so specifying directory name (without -r) will behave differently, and order of the arguments does not matter. o the behaviour is similar to that of "/bin/ls" in that the <path> is taken as relative to the current working directory. E.g. when you are in a directory sub that has a directory dir, you can run git ls-tree -r HEAD dir to list the contents of the tree (that is sub/dir in HEAD). You don't want to give a tree that is not at the root level (e.g. git ls-tree -r HEAD:sub dir) in this case, as that would result in asking for sub/sub/dir in the HEAD commit. However, the current working directory can be ignored by passing --full-tree option. OPTIONS
<tree-ish> Id of a tree-ish. -d Show only the named tree entry itself, not its children. -r Recurse into sub-trees. -t Show tree entries even when going to recurse them. Has no effect if -r was not passed. -d implies -t. -l, --long Show object size of blob (file) entries. -z line termination on output and do not quote filenames. See OUTPUT FORMAT below for more information. --name-only, --name-status List only filenames (instead of the "long" output), one per line. --abbrev[=<n>] Instead of showing the full 40-byte hexadecimal object lines, show only a partial prefix. Non default number of digits can be specified with --abbrev=<n>. --full-name Instead of showing the path names relative to the current working directory, show the full path names. --full-tree Do not limit the listing to the current working directory. Implies --full-name. [<path>...] When paths are given, show them (note that this isn't really raw pathnames, but rather a list of patterns to match). Otherwise implicitly uses the root level of the tree as the sole path argument. OUTPUT FORMAT
<mode> SP <type> SP <object> TAB <file> This output format is compatible with what --index-info --stdin of git update-index expects. When the -l option is used, format changes to <mode> SP <type> SP <object> SP <object size> TAB <file> Object size identified by <object> is given in bytes, and right-justified with minimum width of 7 characters. Object size is given only for blobs (file) entries; for other entries - character is used in place of size. Without the -z option, pathnames with "unusual" characters are quoted as explained for the configuration variable core.quotePath (see git- config(1)). Using -z the filename is output verbatim and the line is terminated by a NUL byte. GIT
