awk search for Quoted strings (')
Hi All,
I have files:
1. abc.sql
'This is a sample file for testing'
This does not have quotations
this also does not have quotations.
and this 'has quotations'.
here I need to list the hard coded strings 'This is a sample file for testing' and
'has quotations'.
So i have written the shell script as below:
#!/bin/sh
x=$(basename $1)
y=$(dirname $1)
echo "filename: $x"
echo "Dir name: $y"
file_ext=${x##*.}
if [ ! -f $x ]; then
printf "File $x is not a valid file"
exit
fi
if [ $file_ext = sql ] || [ $file_ext = pls ] || [ $file_ext = xml ]; then
printf "This file has extension $file_ext\n";
grep -i "'" $x > hard_coded_strings.txt
fi
Here after the script had been executed, the file "hard_coded_strings.txt" has the text,
'This is a sample file for testing'
and this 'has quotations'.
Now i need to get only the data in the quotation marks, and i have used the awk command and i don't understand how do we compare quotation mark(').
awk command is as below:
awk '{a="/'" ; print index ( $0,a ) > "hardcoded.txt"}' hard_coded_strings.txt
I have used all kinds of possibilitis as,
awk '/"'"||*||"'"/ {a=""'"" ; print index ( $0,a ) > "hardcoded.txt"}' hard_coded_strings.txt
Can any one suggest me how do we get the quoted strings.
Thanks,
Kiran.

NAME
shtool-path - GNU shtool command dealing with shell path variables
SYNOPSIS
shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...]
DESCRIPTION
This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments. It
prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found.
OPTIONS
The following command line options are available.
-s, --suppress
Supress output. Useful to only test whether a program exists with the help of the return code.
-r, --reverse
Transform a forward path to a subdirectory into a reverse path.
-d, --dirname
Output the directory name of str.
-b, --basename
Output the base name of str.
-m, --magic
Enable advanced magic search for ""perl"" and ""cpp"".
-p, --path path
Search in path. Default is to search in $PATH.
EXAMPLE
# shell script
awk=`shtool path -p "${PATH}:." gawk nawk awk`
perl=`shtool path -m perl`
cpp=`shtool path -m cpp`
revpath=`shtool path -r path/to/subdir`
HISTORY
The GNU shtool path command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken
over into GNU shtool.
