I have a file called test.txt
I have a pattern file called pattern.txt containing the following
I want to do a count, but have it display the count value preceeding each line like grep -n
so
grep -n -f pattern.txt would show
What I would like to do is have grep count the number of occurances in the file and place that value at the begining of the output so it would look like
3 means abc occured 3 times in the file
2 means def occured 2 times in the file
Is there a function or a clever way to achieve this?
I have the following data:
A
1
2
3
A
4
5
6
A
7
8
9
I want to grep this data with A and 3 lines below it then display them in this format:
A 1 2 3
A 4 5 6
A 7 8 9 (4 Replies)

Folks, is it possible to display only words with grep (or any built-in ultility)?
I have more than 1 pattern to search, say apple & orange
The text goes like this:
So I need to display all the words starting with apple or orange
The output should be:
Any idea? (7 Replies)
Hi
is there a way in grep to display few lines before and after the pattern??
I tried options A and B and after-context and before-context. But they don't work on Solaris platform.
please advise. (13 Replies)
I use grep to check for a string that validates data in a file, it works great but the problem is that the file is becoming too big and gerp has started hurting the response time to users. Since I only need to find the first occurrence I have been looking for ways to stop grep for scanning the rest... (8 Replies)
/usr/xpg4/bin/grep -e "Type" / datarecords.txt

i wanna the output to be

at the end not to appear the filename fom grep command :D :D (3 Replies)
I have a file against which I can grep a string for. I can also check for that string count using wc -l (or grep -c). I need to display the results of both in one output i.e. 'line containing string' and 'count' - what would be the most efficient way of managing this? Thanks in advance. (3 Replies)
i have this line of code that looks for the same file if it is currently running and returns the count.
`ps -eaf -o args | grep -i sfs_pcard_load_file.ksh | grep -v grep | wc -l`
basically it is assigned to a variable
ISRUNNING=`ps -eaf -o args | grep -i sfs_pcard_load_file.ksh |... (6 Replies)
How would I do the following :
Records other than ”ATOM”,”CONNECT”, ”HETATM”, ”TER” and ”END” are considered header records which describe the metadata about the molecule. Use grep to generate the header.

subst
subst(n) Tcl Built-In Commands subst(n)
__________________________________________________________________________________________________________________________________________________NAME
subst - Perform backslash, command, and variable substitutions
SYNOPSIS
subst ?-nobackslashes? ?-nocommands? ?-novariables? string
_________________________________________________________________DESCRIPTION
This command performs variable substitutions, command substitutions, and backslash substitutions on its string argument and returns the
fully-substituted result. The substitutions are performed in exactly the same way as for Tcl commands. As a result, the string argument
is actually substituted twice, once by the Tcl parser in the usual fashion for Tcl commands, and again by the subst command.
If any of the -nobackslashes, -nocommands, or -novariables are specified, then the corresponding substitutions are not performed. For
example, if -nocommands is specified, command substitution is not performed: open and close brackets are treated as ordinary characters
with no special interpretation.
Note that the substitution of one kind can include substitution of other kinds. For example, even when the -novariables option is speci-
fied, command substitution is performed without restriction. This means that any variable substitution necessary to complete the command
substitution will still take place. Likewise, any command substitution necessary to complete a variable substitution will take place, even
when -nocommands is specified. See the EXAMPLES below.
If an error occurs during substitution, then subst will return that error. If a break exception occurs during command or variable substi-
tution, the result of the whole substitution will be the string (as substituted) up to the start of the substitution that raised the excep-
tion. If a continue exception occurs during the evaluation of a command or variable substitution, an empty string will be substituted for
that entire command or variable substitution (as long as it is well-formed Tcl.) If a return exception occurs, or any other return code is
returned during command or variable substitution, then the returned value is substituted for that substitution. See the EXAMPLES below.
In this way, all exceptional return codes are "caught" by subst. The subst command itself will either return an error, or will complete
successfully.
EXAMPLES
When it performs its substitutions, subst does not give any special treatment to double quotes or curly braces (except within command sub-
stitutions) so the script
set a 44
subst {xyz {$a}}
returns "xyz {44}", not "xyz {$a}" and the script
set a "p} q {r"
subst {xyz {$a}}
returns "xyz {p} q {r}", not "xyz {p} q {r}".
When command substitution is performed, it includes any variable substitution necessary to evaluate the script.
set a 44
subst -novariables {$a [format $a]}
returns "$a 44", not "$a $a". Similarly, when variable substitution is performed, it includes any command substitution necessary to
retrieve the value of the variable.
proc b {} {return c}
array set a {c c [b] tricky}
subst -nocommands {[b] $a([b])}
returns "[b] c", not "[b] tricky".
The continue and break exceptions allow command substitutions to prevent substitution of the rest of the command substitution and the rest
of string respectively, giving script authors more options when processing text using subst. For example, the script
subst {abc,[break],def}
returns "abc,", not "abc,,def" and the script
subst {abc,[continue;expr {1+2}],def}
returns "abc,,def", not "abc,3,def".
Other exceptional return codes substitute the returned value
subst {abc,[return foo;expr {1+2}],def}
returns "abc,foo,def", not "abc,3,def" and
subst {abc,[return -code 10 foo;expr {1+2}],def}
also returns "abc,foo,def", not "abc,3,def".
