instead of

... | grep program | grep -v grep

which saves one "grep".

for the "%CPU" have a look at the man-page of the ps-command. The "-o"-option is...

I think this may be what you see -

Hi,

Try this:
sed -i '1s/.*/ HEADER20110101&/' a.txt

echo '2011-01-01 00:00:00' | sed -n 's/[-| |:]//gp'

Try

$ echo "2011-01-01 00:00:00" | sed 's/[ :-]//g'
20110101000000

Is your's gnu date ?

try whether the below command works or not

date -d "1 day ago" +%Y%m%d

Alternate awk..
awk 'NR==1{$0="header\n"$0}1' inputfile

i am adding 123 in the first line of the file called test


$ nawk ' { if (NR==1){printf("123%s\n",$0)} else {print} }' test
123abc
abc
abc
abc
abc

$ cat test
abc
abc
abc

sed "s/ = /=/;s/'/\\\'/g" infile# cat tst
XX = to_date ('9999-12-31 23:59:59', 'YYYY-MM-DD HH24:MI:SS')
# sed "s/ = /=/;s/'/\\\'/g" tst
XX=to_date (\'9999-12-31 23:59:59\', \'YYYY-MM-DD...

XX= echo $XX|sed 's/*situation now*/*what you want*/'


would probably work

See if this works for you:
#!/usr/bin/ksh
typeset -i mFirst5
typeset -i mLast5

mFirstLine=$(head -1 inp_file)
mFirst14=$(echo ${mFirstLine} | cut -d'|' -f1-4)
mFirst5=$(echo ${mFirstLine} |...

ruby -ne 'print if /^[DH]/' file

echo "DATA" | grep "^[DH]"

grep command pattern for lines that begin with D or H:
$ grep '^[DH]' inf_files >out_file

in Korn shell (#!/bin/ksh) , you can use if condition with the operators

-ot|older than
-nt|newer thanon files

Example :

# touch titi
# touch toto
# stat titi
File: `titi'
Size: 0 ...

if running linux :
ls -m input---------- Post updated at 12:22 PM ---------- Previous update was at 12:13 PM ----------

or
ls -m input | tr -d ' '

ls |tr '\n' ','
