Hello,

I have a bash script that puts the output of the history command and the crontab into a file and a perl script thats sends it via email.

The bash script is the following:

Code:

#!/bin/bash

FILE=history_crontab
HISTFILE=~/.bash_history
cat /dev/null > $FILE

set -o history

echo "Command history and crontab for User:  `whoami`" >> $FILE
echo >> $FILE
echo >> $FILE

echo "History: " >> $FILE
echo >> $FILE

history >> $FILE
echo >> $FILE

echo "Crontab: "  >> $FILE
echo >> $FILE

history -c
echo "" > $HISTFILE

crontab -l >> $FILE

Though, some times I get hashes followed by numbers...

Code:

1  #1326782483
     2  cd bin/pots_instances/new
     3  #1326782491
     4  less all_cards_columns 
     5  #1326782503
     6  ./make_columns.sh times_0112
     7  #1326785639
     8  ./make_columns.sh times_0113
     9  #1326785891

    34  cd test
    35  #1326806958
    36  ls logs 
    37  #1326806972
    38  cd cdb-meminfo
    39  #1326806977
    40  cd files/
    41  #1326806982
    42  less Galatsi_2.txt 
    43  #1326806993
    44  cd ..
    45  #1326806994
    46  ls
    47  #1326807015
    48  tar jxvf cdb-meminfo.tar.bz2 
    49  #1326807048
    50  unzip cdb-meminfo.zip 
    51  #1326807051
    52  less cdb-meminfo/files/Keratsini_1.txt 
    53  #1326807058
    54  rm -r cdb-meminfo
    55  #1326808762
    56  exit

Does anybody know why?

Thanks,

George.

If I had to guess, those #s are date/time stamps for history.

Code:

date -d @1326808762

= Tue Jan 17 08:59:22 EST 2012

If you want history plain, I use

Code:

unset HISTTIMEFORMAT
alias hist='history | sed '\''s/^[ 0-9]* //'\'''
hist

Code:

using that technique comes out to

Code:
