How to delete everything present on left (or right) of a substring?
Hello,
I have list of lines from which i am trying to pick a sub string and want to put that into a csv file, the sub string i want to extract is at the middle of the line, i was wondering how can i delete everything that is present left/right of a sub string. I have tried sed, cut and awk, but i couldn't get desired results.
Below are few lines, from which i am trying to pick PXCNUMBER_1 and append them to a csv file.
using awk and cut i got this result, due to some inconsistency in the lines i failed to pick the PXCNUMBERS_1, precisely as you could see there is MSGS_ in the last line before PXCNUMBERS_1 .
Desired results are
I know i could use sed to replace MSGS in the last line to empty, but there are more lines than i have showed above, and i was also curious to know if there is any command to cut everything left/right of a sub string. any pointers would be great help
I have a script which loop through a directory then report any file matches the given pattern,
say, the pattern is "a2006", this file would be returned
a20061101.txt
I would like to know how can I get the remaining of the filename, so
a20061101txt - a2006 = 1101.txt
Can anybody help? Thank... (2 Replies)

df -k :
/dev/vx/dsk/dlds02vg/dlds02oralv 4194304 4194304 0 100% /dlds02/lds/oracle

grep
GREP(1) General Commands Manual GREP(1)NAME
grep - search a file for a pattern
SYNOPSIS
grep [ option ... ] pattern [ file ... ]
DESCRIPTION
Grep searches the input files (standard input default) for lines (with newlines excluded) that match the pattern, a regular expression as
defined in regexp(6). Normally, each line matching the pattern is `selected', and each selected line is copied to the standard output.
The options are
-c Print only a count of matching lines.
-h Do not print file name tags (headers) with output lines.
-i Ignore alphabetic case distinctions. The implementation folds into lower case all letters in the pattern and input before interpre-
tation. Matched lines are printed in their original form.
-l (ell) Print the names of files with selected lines; don't print the lines.
-L Print the names of files with no selected lines; the converse of -l.
-n Mark each printed line with its line number counted in its file.
-s Produce no output, but return status.
-v Reverse: print lines that do not match the pattern.
Output lines are tagged by file name when there is more than one input file. (To force this tagging, include /dev/null as a file name
argument.)
Care should be taken when using the shell metacharacters $*[^|()= and newline in pattern; it is safest to enclose the entire expression in
single quotes '...'.

Exit status is null if any lines are selected, or non-null when no lines are selected or an error occurs.
