grp
is a Unix CLI that facilitates breaking text into groups of characters with a variety of options
and also offers formatting numbers with digit grouping (thousands separators) based on the active locale.
See the examples below, concise usage information further below, or read the manual.
# By default, break a string into space-separated groups of 3 chars.,
# starting from the right (end).
$ grp 1000000 2000
1 000 000
2 000
# Use proper number formatting (separation with locale-specific thousands
# separators) with -n; example output from the U.S. English locale:
$ grp -n 1000000 1999.99
1,000,000
1,999.99
# Break input into lines of 3 characters each, starting from the left:
$ grp -c 3 -s $'\n' -l abcdefgh
abc
def
gh
# Insert a '.' between characters:
$ grp -c 1 -s . abcdef
a.b.c.d.e.f
# Enclose each character in square brackets:
$ grp -c 1 -f '[%s]' abc
[a][b][c]
# Format text as a US telephone number:
$ echo '6085277865' | grp -f '+1 (%s) %s-%s' -c 3,3,4
+1 (608) 527-7865
# Break the input into repeating groups of 2 and 1 char. each:
$ grp -l -c 2,1+ -s / abcdefgh
ab/c/de/f/gh
Supported platforms
With Node.js or io.js installed, install the package as follows:
[sudo] npm install grp-cli -g
Note:
sudo
depends on how you installed Node.js / io.js and whether you've changed permissions later; if you get an EACCES
error, try again with sudo
.-g
ensures global installation and is needed to put grp
in your system's $PATH
.grp
.chmod +x grp
.$PATH
, such as /usr/local/bin
(OSX) or /usr/bin
(Linux).Find concise usage information below; for complete documentation, read the manual online or,
once installed, run man grp
(grp --man
if installed manually).
$ grp --help
Format numbers with digit grouping:
grp -n [-t <term>] [<num>...]
Break text into groups of characters:
grp [-l | -r] [-c <count>] [-s <sep> | -f <fmt>] [-t <term>] [<txt>...]
Options:
-n apply locale-aware digit grouping to input numbers
-t <term> terminator to append to each argument's result; default: \n
-l, -r start grouping from left / right (default)
-c <count> count of chars. per group - may be comma-separated list
-s <sep> either: separator to place between groups; default: a space
-f <fmt> or: printf-style format string to apply to groups
