Shell Scripting , need to search and print a line that contains a specific pattern
Take example of below file.
abc.txt
Now i have a variable that contains "nas1:/abc/test/test1" value , so i need to search the above file for this variable and print only this line.
output expected :- nas1:/abc/test/test1 /test
i tried cat abc.txt | grep -w "nas1:/abc/test/test1 " , its not working for few linux servers , so can i have some commands that can run on all distros.

TEST(1) General Commands Manual TEST(1)NAME
test - set status according to condition
SYNOPSIS
test expr
DESCRIPTION
Test evaluates the expression expr. If the value is true the exit status is null; otherwise the exit status is non-null. If there are no
arguments the exit status is non-null.
The following primitives are used to construct expr.
-r file True if the file exists (is accessible) and is readable.
-w file True if the file exists and is writable.
-x file True if the file exists and has execute permission.
-e file True if the file exists.
-f file True if the file exists and is a plain file.
-d file True if the file exists and is a directory.
-s file True if the file exists and has a size greater than zero.
-t fildes True if the open file whose file descriptor number is fildes (1 by default) is the same file as /dev/cons.
-A file True if the file exists and is append-only.
-L file True if the file exists and is exclusive-use.
-Tfile True if the file exists and is temporary.
s1 = s2 True if the strings s1 and s2 are identical.
s1 != s2 True if the strings s1 and s2 are not identical.
s1 True if s1 is not the null string. (Deprecated.)
-n s1 True if the length of string s1 is non-zero.
-z s1 True if the length of string s1 is zero.
n1 -eq n2 True if the integers n1 and n2 are arithmetically equal. Any of the comparisons -ne, -gt, -ge, -lt, or -le may be used in place
of -eq. The (nonstandard) construct -l string, meaning the length of string, may be used in place of an integer.
a -nt b True if file a is newer than (modified after) file b.
a -ot b True if file a is older than (modified before) file b.
f -older t True if file f is older than (modified before) time t. If t is a integer followed by the letters y(years), M(months), d(days),
h(hours), m(minutes), or s(seconds), it represents current time minus the specified time. If there is no letter, it represents
seconds since epoch. You can also concatenate mixed units. For example, 3d12h means three days and twelve hours ago.
These primaries may be combined with the following operators:
! unary negation operator
-o binary or operator
-a binary and operator; higher precedence than -o
( expr ) parentheses for grouping.
The primitives -b, -u, -g, and -s return false; they are recognized for compatibility with POSIX.
Notice that all the operators and flags are separate arguments to test. Notice also that parentheses and equal signs are meaningful to rc
and must be enclosed in quotes.
EXAMPLES
Test is a dubious way to check for specific character strings: it uses a process to do what an rc(1) match or switch statement can do. The
first example is not only inefficient but wrong, because test understands the purported string "-c" as an option.
if (test $1 '=' "-c") echo OK # wrong!
A better way is
if (~ $1 -c) echo OK
Test whether is in the current directory.
test -f abc -o -d abc
