A GNU/Linux or Unix program built with fpm that finds pathnames to commands in the current search path and displays them, or applies a command to them.
Build fcmd(1) using fpm(1):
git clone https://github.com/urbanjost/apps
cd apps/fcmd
fpm install
fcmd --helpfcmd(1f) - [FUNIX:FILESYSTEM] find the pathname of commands and optionally perform commands on them. (LICENSE:MIT)
fcmd [commands(s) [--wild] [ --first][--ignorecase][--test]
[ --cmd COMMAND;COMMAND,COMMAND;... ]|[--long]|[--vi]
[ --help|--version]
fcmd(1f) takes one or more command names. For each of its arguments by default it prints to stdout the path of the executables that would have been executed when this argument had been entered at the shell prompt. It does this by searching for an executable or script in the directories listed in the environment variable PATH.
Optionally, commands can be specified to act on the path names found.
If no options are supplied the current search path is displayed one directory per line.
command(s) names of commands to locate. simple globbing with *
and ? is allowed if the names are quoted.
--ignorecase,i ignore case of input command(s)
--first,-f locate first match of each executable name expression, not all.
--cmd,-c invoke the command on the files found. If present with
no parameter the desired command is assumed to be
the default editor (useful for finding and looking
at scripts). The editor command is looked for in the
environment variables FCEDIT, EDITOR and then VISUAL.
if not found, "vi" is used.
Multiple commands delimited by a semi-colon and/or a colon
may be used.
Abbreviations for common --cmd options:
--long,l abbreviation for "--cmd 'ls -l'"
--vi abbreviation for "--cmd 'vim'"
--ok Prompt for a y/n answer before executing the list of
commands on each file found.
--test,-t print first command found and stop
--wild,-w add asterisk as a suffix and prefix to all command names
being searched for.
--version,-v Print version information on standard output then
exit successfully.
--help,-h Print usage information on standard output then
exit successfully.
Sample commands
fcmd ls # find path to ls(1) command
fcmd '*sum*' # find all commands containing "sum"
fcmd sum -w # also find all commands containing "sum"
fcmd '*' # list all commands in search path
fcmd gunzip -c # edit the script gunzip(1)
fcmd ls dir # find both commands
# find all commands in path and a man-page if they have one
fcmd '*' -c whereis
# find a command and use the commands file(1) and stat(1) on the
# pathnames found.
fcmd pwd -c 'file;stat'
Common commands to use are "cat -vet", "ls -l", "strings", "what",
"sum", "whereis", "stat", "wc", "ldd", and "file".
