Cron Job failure - No such file or directory
Hi all,

I'm having an issue with a script i wrote to pull information from the Amazon AWS API. Basically the script takes arguments from the command line and attempts to grab user information for each AWS access group. The command is issued like this:

# sh awsReport.sh <outputFileName> <AWS Authentication Profile Name>

Code for the script:
Code:
#!/bin/bash
# AWS user reports
# user list as array (per account)

usage () {
        echo $'\t'"Usage: $0 OUTPUT_FILE_NAME AWS_PROFILE_NAME"
        exit $1
}

#Get date, append to file name, append CSV 
_now=$(date +"%m_%d_%Y")
OUTPUT_FILE="$1_$_now.csv"; shift
PROFILE="$1"; shift
[[ "$OUTPUT_FILE" != "" ]] || { echo $'\n\n\t'"ERROR: no output file defined. Exiting."; usage 1; }
[[ "$PROFILE" != "" ]] || { echo $'\n\n\t'"ERROR: no AWS Profile file defined. Exiting."; usage 2; }

# check for file...
[[ -f "$OUTPUT_FILE" ]] && echo $'\n\n'"*****  Report Date: (date) *****" >> $OUTPUT_FILE

#Query AWS
USERS=(`aws iam list-users --profile $PROFILE --output text|awk '{print $6}'`)

for u in ${USERS[@]}; do
    echo "UserName = "$u >> $OUTPUT_FILE
    echo "GroupMembership:" >> $OUTPUT_FILE
    echo -n $'\t';aws iam list-groups-for-user --profile $PROFILE --output json --user-name $u|jq 'reduce .Groups[].GroupName as $item (""; . +$item+", ")' >> $OUTPUT_FILE
    echo "*************" >> $OUTPUT_FILE
done

#mail report to security
mail -s "AWS User Report" -a /root/Scripts/$OUTPUT_FILE security@someCompany.com < /root/Scripts/$OUTPUT_FILE
exit 0

Crontab file:
Code:
#!/bin/bash
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=security@servicesource.com
HOME=/
* * * * * /root/Scripts/awsReportTest.sh awsUserReportV1 awsV1prod

And finnaly the Crontab error i'm getting:

Code:
/root/Scripts/awsReportTest.sh: line 28: /root/Scripts/awsUserReportV1_09_23_2014.csv: No such file or directory

When I run the script from the CLI everything works file. I can change the arguments to run the script for our other environments and it works fine. I get this error only when the script is executed from Cron, any ideas?

Thanks,
Choco

The job started by a cron will have user's home directory as current directory, I'd guess when you run your commands from CLI your current directory is different; Try to add cd /your/target/dir; before your command in the crontab entry, like so:

Code:
 
 1 2 * * * cd /your/target/dir; your_script_name;

Thank you for the reply, migurus. I edited the crontab as you suggested and am getting the error:

Code:
awsReportTest.sh: line 18: aws: command not found
awsReportTest.sh: line 28: /root/Scripts/awsUserReportV2testfile: No such file or directory

It seems that the file is actually not being created when run as a cron job. When run manually from the command line ie:
Code:
/root/Scripts/# sh awsReportTest.sh awsUserReportFile awsAccessProfile

the file gets created correctly.

I did an ls on the directory after the cron and it's not creating the file 'awsUserReportFile'....

Any other suggestions?

command not found meant system did not see the executable file you are trying to run - the path to it is probably set in your .profile, or some other way. Keep in mind that when cron creates very limited environment for its processes, the .profile (or another startup) is not used by cron. you need to explicitely specify where the executable file is, like cd /your/path; /your/exec/path/execfile arguments ... ;
