I haven't tried this, but it may get you a step closer to what you want.
Code:
for f in $(find . -name SOMETHING*); do
g="modified-$f"
cp -iv $f $g
while head -n1 $g|egrep -qv '^Data[[:print:]]{20}' && test -s $g; do
sed 1d -i $g
done
done
It loops through all the files found, makes a copy, and chops off the first line as long as it doesn't start with 'Data' followed by 20 printable characters.
Note that egrep -qv does not print any output (-q) and returns true if it does not (-v) find the regex. And test -s returns true if the file is greater than zero size.
Hi folks. None of the conventional methods are working for my dilemma:
I have a file in my root directory that has a name comprised of strange characters. When I do an ls, it just hangs at that file until I do a Cntrl-C.

Hello ,
I'm trying to split a file which contains a single very long line.
My aim is to split this single line each 120 characters.
I tried with the sed command :
`cat ${MYPATH}/${FILE}|sed -e :a -e 's/^.\{1,120\}$/&\n/;ta' >{MYPATH}/${DEST}`
but when I wc -l the destination file it is... (2 Replies)
Hello all,
I'm new to UNIX and new to this forum, so forgive my lack of knowledge. I'm new with editing in vi so I FTP scripts to a Windows machine and edit the script in notepad (when I need to do something quickly). Sometimes when I FTP the script back to the UNIX box, strange characters... (4 Replies)
Hi, I have a bash script and I am looking for a command that will merge specific lines together.
Sample Data:

}

The idea is that it trundles through a large directory structure looking for files which are named '1.' and then... (3 Replies)
Hello unix users :)
I am trying to grep a string from a file that both the file and the string may have characters in them that are quite... strange, like würzburger.
Well, bash reads this as
W%C3%BCrzburger
For example, if i do
wget W%C3%BCrzburger
the output is:

zipgrep
ZIPGREP(1L)ZIPGREP(1L)NAME
zipgrep - search files in a ZIP archive for lines matching a pattern
SYNOPSIS
zipgrep [egrep_options] pattern file[.zip] [file(s) ...] [-x xfile(s) ...]
DESCRIPTION
zipgrep will search files within a ZIP archive for lines matching the given string or pattern. zipgrep is a shell script and requires
egrep(1) and unzip(1L) to function. Its output is identical to that of egrep(1).
ARGUMENTS
pattern
The pattern to be located within a ZIP archive. Any string or regular expression accepted by egrep(1) may be used. file[.zip] Path
of the ZIP archive. (Wildcard expressions for the ZIP archive name are not supported.) If the literal filename is not found, the
suffix .zip is appended. Note that self-extracting ZIP files are supported, as with any other ZIP archive; just specify the .exe
suffix (if any) explicitly.
[file(s)]
An optional list of archive members to be processed, separated by spaces. If no member files are specified, all members of the ZIP
archive are searched. Regular expressions (wildcards) may be used to match multiple members:
* matches a sequence of 0 or more characters
? matches exactly 1 character
[...] matches any single character found inside the brackets; ranges are specified by a beginning character, a hyphen, and an end-
ing character. If an exclamation point or a caret (`!' or `^') follows the left bracket, then the range of characters within
the brackets is complemented (that is, anything except the characters inside the brackets is considered a match).
(Be sure to quote any character that might otherwise be interpreted or modified by the operating system.)
[-x xfile(s)]
An optional list of archive members to be excluded from processing. Since wildcard characters match directory separators (`/'),
this option may be used to exclude any files that are in subdirectories. For example, ``zipgrep grumpy foo *.[ch] -x */*'' would
search for the string ``grumpy'' in all C source files in the main directory of the ``foo'' archive, but none in any subdirectories.
Without the -x option, all C source files in all directories within the zipfile would be searched.
OPTIONS
All options prior to the ZIP archive filename are passed to egrep(1).
