Awk printf format specifiersFor each percent sign and format specifier , there must be a corresponding argument. To print a literal percent sign, two percent signs must be used. See Table 6.2 for a list of printf conversion characters and Table 6.3 for printf modifiers. The format specifiers are preceded by a percent sign; see Table 6.4 for a list of printf format specifiers.FIELDS, RECORDS, AND VARIABLES IN AWK The format argument (or format string) defines how each of the other arguments will be output. It uses format specifiers to do this, including %s to output a string and %d to output a decimal number. For each percent sign and format specifier , there must be a corresponding argument. To print a literal percent sign, two percent signs must be used. See Table 6.2 for a list of printf conversion characters and Table 6.3 for printf modifiers. The format specifiers are preceded by a percent sign; see Table 6.4 for a list of printf format specifiers.AWK - Overview. AWK is an interpreted programming language. It is very powerful and specially designed for text processing. Its name is derived from the family names of its authors − Alfred Aho, Peter Weinberger, and Brian Kernighan.. The version of AWK that GNU/Linux distributes is written and maintained by the Free Software Foundation (FSF); it is often referred to as GNU AWK.As in C-language, AWK also has format specifiers. The AWK version of the printf statement accepts the following conversion specification formats − %c. It prints a single character. If the argument used for %c is numeric, it is treated as a character and printed. Otherwise, the argument is assumed to be a string, and the only first character of that string is printed. Example [jerry]$ awk 'BEGIN { printf "ASCII value 65 = character %c ", 65 }' Output Oct 07, 2018 · Format Specification Syntax: printf and wprintf Functions.

Note, that awk gives us an access to the first 99 of fields in a single line.This format is also useful for running short or medium-sized @command{awk} programs from shell scripts, because it avoids the need for a separate file for the @command{awk} program. A self-contained shell script is more reliable because there are no other files to misplace. awk printf formatting using string format specifier.

The query format is similar to a C style printf string, which the printf(2) man page provides a good introduction to. However, as RPM already knows the type of data that is being printed, you must omit the type specifier. Therefore, another utility that reads that output as its input must be prepared to parse the data using scanf, awk, and so on. The ' ' character is used when exactly one <space> is output. The treatment of integers and spaces is different from the printf () function in that they can be surrounded with <blank> characters. There are many additional details regarding the use of printf to format output, which you can find in the user manual. Spend some time formatting output differently.
